Check Digit Verification of cas no

The CAS Registry Mumber 139962-69-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,6 and 2 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139962-69:
(8*1)+(7*3)+(6*9)+(5*9)+(4*6)+(3*2)+(2*6)+(1*9)=179
179 % 10 = 9
So 139962-69-9 is a valid CAS Registry Number.

Azaindole synthesis through dual activation catalysis with N-heterocyclic carbenes

Sharma, Hayden A.,Todd Hovey,Scheidt, Karl A.

, p. 9283 - 9286 (2016)

A convergent, transition-metal-free synthesis of 2-aryl-azaindoles has been developed. The interception of a reactive aza-ortho-azaquinone methide intermediate by an acyl anion equivalent generated through carbene catalysis provides high yields, a wide substrate scope, and the synthesis of previously inaccessible azaindoles.
