You are wrong. CAS numbers extracted from Wikipedia are not subject to
the GFDL, since they lack any copyright protection.

Including that PD data into Wikipedia does not "un-PD" it.. People are
and were free to use CAS numbers without the need to ask for
permission long before the data was inserted into Wikipedia.
