Check Digit Verification of cas no

The CAS Registry Mumber 1256159-59-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,1,5 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1256159-59:
(9*1)+(8*2)+(7*5)+(6*6)+(5*1)+(4*5)+(3*9)+(2*5)+(1*9)=167
167 % 10 = 7
So 1256159-59-7 is a valid CAS Registry Number.

Gold(I) catalyzes the intermolecular hydroamination of alkynes with imines and produces α,α′, N-triarylbisenamines: Studies on their use as intermediates in synthesis

Leyva-Perez, Antonio,Cabrero-Antonino, Jose R.,Cantin, Angel,Corma, Avelino

, p. 7769 - 7780 (2010)

α,α′,N-Triarylbisenamines have been efficiently formed and isolated for the first time. The synthesis is based on an unprecedented gold(I)-catalyzed double intermolecular hydroamination between N-arylamines and aryl alkynes. This reaction constitutes a ne
