Wikipedia:Articles for deletion/List of EINECS substances 200-xxx-x
the EC number system itself is notable, being used Europe-wide, and so adding EC numbers alongside CAS numbers to infoboxes of |notable chemicals seems reasonable.  However, a listing of all substances by EC number seems to me to be fairly useless... and as DGG has noted, a violation of OTDIRECTORY.  I have no idea why the Europeans couldn't just use CAS numbers, but I suppose that's a topic for somewhere else
