CAS 75-28-5 · CAS 106-97-8 · EC 200-857-2 · EC 203-448-7 · Index No 601-004-00-0 · Index No 601-004-01-8
Where EC 203-448-7 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.
