CAS 101-77-9 · EC 202-974-4 · Index No 612-051-00-1
Where CAS 101-77-9 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.
