Check Digit Verification of cas no

The CAS Registry Mumber 56915-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,1 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56915-04:
(7*5)+(6*6)+(5*9)+(4*1)+(3*5)+(2*0)+(1*4)=139
139 % 10 = 9
So 56915-04-9 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.
