The EINECS number (for European Inventory of Existing Chemical Substances) is a registry number given to each chemical substance commercially available in the European Union between 1 January 1971 and 18 September 1981. A chemical substance is a Material with a definite chemical composition. The European Union ( EU) is a political and economic union of twenty-seven member states, located primarily in New Year See also New Year The Ancient Romans began their consular year on January 1st since 153 BC Year 1971 ( MCMLXXI) was a Common year starting on Friday (link will display full calendar of the 1971 Gregorian calendar. Events 96 - Nerva is proclaimed Roman Emperor after Domitian is assassinated Year 1981 ( MCMLXXXI) was a Common year starting on Thursday (link displays the 1981 The inventory was created by Directive 67/548/EEC concerning the labeling of dangerous substances: the EINECS number(s) must appear on the label and the packaging of dangerous substances. Council Directive 67/548/EEC of 27 June 1967 on the approximation of laws regulations and administrative provisions relating to the classification packaging and labelling

As from 19 September 1981, the inventory has been replaced by the European List of Notified Chemical Substances (ELINCS). Events 335 - Dalmatius is raised to the rank of Caesar by his uncle Constantine I. Year 1981 ( MCMLXXXI) was a Common year starting on Thursday (link displays the 1981 All "new" substances brought on to the European market are allocated an ELINCS number after their notification to the European Chemicals Bureau. The EINECS number (for European Inventory of Existing Chemical Substances) is a registry number given to each Chemical substance commercially available in the The Toxicology and Chemical Substances ( TCS) that is the focal point for data and the assessment procedure on dangerous Chemicals within the European Union The ELINCS number is also obligatory on labels and packaging. The EINECS number (for European Inventory of Existing Chemical Substances) is a registry number given to each Chemical substance commercially available in the

And the No-Longer Polymers (NLP): Substances to be included in this list have been on the EU market between September 18, 1981, and October 31, 1993 and satisfy the requirement that they were considered to be polymers under the reporting rules for EINECS but are no longer considered to be polymers under the 7th amendment. Therefore to create the no-longer polymer list industry was asked to submit their candidates. The attached list is based on these submissions.

The term EC number is now preferred to the outmoded "EINECS/ELINCS/NLP number" designations, but this is not to be confused with the Enzyme Commission EC numbers. The terms EC-No and EC# refer to the seven-digit code (sometimes called the EC number) that has been allocated by the Commission of the European Communities This article is about the Enzyme Commission codes For the European Commission system for coding chemicals see EC-No.

There are 100,204 different substances in the EINECS, 4,381 in ELINCS (2006 Publication) and 703 in NLP.

Format

An EINECS number is a seven-digit system number of the form 2XX-XXX-X or 3XX-XXX-X, starting at 200-001-8.

An ELINCS number is a seven-digit system number of the form 4XX-XXX-X, starting at 400-010-9.

A NLP number is a seven-digit system number of the form 5XX-XXX-X, starting at 500-001-0.

The EINECS/ELINCS/EC Number may be written in a general form as:

  NNN-NNN-R
  123-456-0

In which R represents the check digit and N represents a fundamental sequential number. The check digit is derived from the following formula:

  1N + 2N + 3N + 4N + 5N + 6N        R
  --------------------------- = Q + --
                11                  11

In which Q represents an integer which is discarded. A check digit is a form of Redundancy check used for Error detection, the decimal equivalent of a binary Checksum.
