EC number[edit]

This identifier is authorised (maintained) by or via ECHA. However, their document on InfoCards pdf says that The EC or list number is the primary substance identifier used by ECHA (where list number is and extension of EC number, using distinct opening digit 6-9). (pattern \d{3}\-\d{3}\-.\d). The example substance Bis(2-ethylhexyl) phthalate has EC number 204-211-0, but is linked through "id" 100.003.829. CAN someone enlighten this? -DePiep (talk) 07:47, 1 March 2016 (UTC)[reply]

ECHA had earlier replied the following by e-mail (extract):
There is, unfortunately, no direct link between the identifiers for an Info Card (e.g. 100.013.852) and the EC number, CAS number, or the substance name.
… for a work-around: The list of Registered Substances in download-format includes the link to the relevant Info Card for a substance. The number of results within one download is currently limited to 10.000 (the limit is under review but we do not know by when the issue will be solved): http://echa.europa.eu/information-on-chemicals/registered-substances

Job for wikidata then, useless route to add this locally. -DePiep (talk) 09:23, 1 March 2016 (UTC)[reply]
There is a link between all of them in the CoSing Database http://ec.europa.eu/growth/tools-databases/cosing/index.cfm?fuseaction=search.details_v2&id=40524. For which we have a property https://www.wikidata.org/wiki/Property:P3073. Note that the CoSing db is available for matching --Teolemon (talk) 12:33, 2 October 2016 (UTC)[reply]
