Check Digit Verification of cas no

The CAS Registry Mumber 1377578-81-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,7,5,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1377578-81:
(9*1)+(8*3)+(7*7)+(6*7)+(5*5)+(4*7)+(3*8)+(2*8)+(1*1)=218
218 % 10 = 8
So 1377578-81-8 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 (2016/07/25)

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.
