Check Digit Verification of cas no
The CAS Registry Mumber 73984-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,8 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 73984-72:
(7*7)+(6*3)+(5*9)+(4*8)+(3*4)+(2*7)+(1*2)=172
172 % 10 = 2
So 73984-72-2 is a valid CAS Registry Number.

New Routes to Hexafluorocyclopentadiene and Related Compounds
Soelch, Richard R.,Mauer, George W.,Lemal, David M.
, p. 5845 - 5852 (2007/10/02)
Hexafluorocyclopentadiene (1) has been synthesized in two steps from pentafluorophenol (2) by fluorination followed by flash vacuum pyrolysis of the resulting hexafluorocyclohexadienones 3 and 4.Similar pyrolysis of 6-chloropentafluorocyclohexadienone (13) gave an equilibrium mixture of 1- and 2-chloropentafluorocyclopentadiene (15 and 16), presumably via the 5-chloro isomer.Flash vacuum pyrolysis of tetrafluoro-o-benzoquinone 17 yielded tetrafluorocyclopentadienone (20).Hexafluorocyclopentadiene was also prepared via a ring-expansion route which entailed cycloaddition (accompanied by rearrangement) of bromotrifluoroethylene to tetrafluorocyclopropene followed by reductive debromofluorination.
