CAS 109-99-9 · EC 203-726-8 · Index No 603-025-00-0
Where CAS 109-99-9 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.
