CAS 3846-71-7 · EC 223-346-6

Where CAS 3846-71-7 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.
