Check Digit Verification of cas no
The CAS Registry Mumber 2251-83-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2251-83:
(6*2)+(5*2)+(4*5)+(3*1)+(2*8)+(1*3)=64
64 % 10 = 4
So 2251-83-4 is a valid CAS Registry Number.

Fluorination with Complex Metal Fluorides. Part 5. Fluorination of Nitriles over Caesium Tetrafluorocobaltate(III)
Phull, Gurjeet S.,Plevey, Raymond G.,Rendell, Richard W.,Tatlow, John Colin
, p. 1507 - 1511 (2007/10/02)
Benzonitrile and the isomers of benzenedicarbonitrile (phthalo-, isophthalo-, and terephthalo-nitrile) have been fluorinated over caesium tetrafluorocobaltate(III) at elevated temperatures to give a mixtures containing undecafluorocyclohexanecarbonitrile.In addition the dinitriles gave decreasing yields (1,4- > 1,3- > 1,2-) of the corresponding cyclohexanedircarbonitriles.Some reactions (addition, defluorination, hydrolysis, and reduction) of undecafluorocyclohexanecarbonitrile are described.
