There's likely a common sense compromise, like including the CAS numbers but not creating [[List of chemical compounds by CAS number]] or something that all sides would agree to.
Phil's got this exactly right. The objection of theirs that started this thread was *not* that we are using CAS numbers, but rather that some editors over at Wikiproject Chemistry were maybe using the proprietary SciFinder tool as part of a verification project.
No one's asking us to remove any CAS numbers.
