Check Digit Verification of cas no

The CAS Registry Mumber 91639-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,6,3 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91639-77:
(7*9)+(6*1)+(5*6)+(4*3)+(3*9)+(2*7)+(1*7)=159
159 % 10 = 9
So 91639-77-9 is a valid CAS Registry Number.

Benzamides were converted into benzonitriles with BrCCl3- PPh3-Et3N in CH2Cl2 in an Appel-type reaction. Benzaldoximes could be transformed to benzonitriles under identical conditions. It was found that the reaction system BrCCl3-(2 equiv.)PPh3 was also suitable for these transformations with PPh 3 replacing Et3N.
