Check Digit Verification of cas no

The CAS Registry Mumber 1236131-38-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,6,1,3 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1236131-38:
(9*1)+(8*2)+(7*3)+(6*6)+(5*1)+(4*3)+(3*1)+(2*3)+(1*8)=116
116 % 10 = 6
So 1236131-38-6 is a valid CAS Registry Number.

Heteroatom-directed alkylcyanation of alkynes

Nakao, Yoshiaki,Yada, Akira,Hiyama, Tamejiro

supporting information; experimental part, p. 10024 - 10026 (2010/10/04)

Alkanenitriles having a heteroatom such as nitrogen, oxygen, and sulfur at the γ-position are found to add across alkynes stereo-and regioselectively by nickel/Lewis acid catalysis to give highly substituted acrylonitriles. The heteroatom functionalities likely coordinate to the nickel center to make oxidative addition of the C-CN bonds of the alkyl cyanides kinetically favorable, forming a five-membered nickelacycle intermediate and, thus, preventing β-hydride elimination to allow the alkylcyanation reaction.
