EC 234-190-3 sodium dichromate

CAS 7789-12-0 · CAS 10588-01-9 · EC 234-190-3 · Index No 024-004-00-7 · Index No 024-004-01-4

Where EC 234-190-3 appears: every table entry that prints it among its identifiers, in the newest version of each act this record holds, and every recorded change to those entries. Many entries name a group of substances and print no number, so absence here is not absence from the law. Not legal advice.
