The "EC#" designation supersedes the outmoded EINECS and ELINCS designations, and the EC# codes include those on the so-called No-longer Polymers List, a list of substances that were on the European market between 18 September 1981 and 31 October 1993 and at the time were regarded as polymers, but are no longer regarded as such. FORMAT The EC# is made up of seven digits according to the pattern xxx-xxx-x. EINECs numbers start with number 200-001-8. ELINCS numbers start with 400-010-9 Numers in the ''No-longer Polymers List'' start with 500-001-0. The EC/EINECS/ELINCS Number may be written in a general form as: NNN-NNN-R 123-456-0 in which R is the check digit and N represents a fundamental sequential number. The check digit is the Remainder of the following sum after division by 11: N1 + 2×N2 + 3×N3 + 4×N4 + 5×N5 + 6×N6 SEE ALSO EXTERNAL LINK
