Check Digit Verification of cas no

The CAS Registry Mumber 1325399-04-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,5,3,9 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1325399-04:
(9*1)+(8*3)+(7*2)+(6*5)+(5*3)+(4*9)+(3*9)+(2*0)+(1*4)=159
159 % 10 = 9
So 1325399-04-9 is a valid CAS Registry Number.

Selective Csp2-Csp bond cleavage: The nitrogenation of alkynes to amides

Qin, Chong,Feng, Peng,Ou, Yang,Shen, Tao,Wang, Teng,Jiao, Ning

, p. 7850 - 7854 (2013)

Breakthrough: A novel catalyzed direct highly selective C sp 2-C sp bond functionalization of alkynes to amides has been developed. Nitrogenation is achieved by the highly selective C sp 2-Csp bond cleavage of aryl-substituted alkynes. The oxidant-free and mild conditions and wide substrate scope make this method very practical.
