Check Digit Verification of cas no

The CAS Registry Mumber 79457-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,5 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79457-97:
(7*7)+(6*9)+(5*4)+(4*5)+(3*7)+(2*9)+(1*7)=189
189 % 10 = 9
So 79457-97-9 is a valid CAS Registry Number.

Azomethine Imines by Reaction of Diphenylketene with Azodicarboxylates

Fahr, Egon,Buettner, Ehrfried,Keil, Karl-Heinz,Markert, Juergen,Scheckenbach, Franz,et al.

, p. 1433 - 1444 (2007/10/02)

The reaction of diphenylketene with azodicarboxylates yields azomethine imines 4 which show 1,3-dipolaric reactivity: addition of diphenylketene yields the 2:1 adduct 8, addition of phenylisocyanate productes 7, and dimerization leads to 5.
