CAS 330-54-1 · EC 206-354-4 · Index No 006-015-00-9

Where EC 206-354-4 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.
