1397290-31-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1397290-31-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,7,2,9 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1397290-31:
(9*1)+(8*3)+(7*9)+(6*7)+(5*2)+(4*9)+(3*0)+(2*3)+(1*1)=191
191 % 10 = 1
So 1397290-31-1 is a valid CAS Registry Number.

Palladium-catalyzed C(sp2) - H cyanation using tertiary amine derived isocyanide as a cyano source

Peng, Jiangling,Zhao, Jiaji,Hu, Ziwei,Liang, Dongdong,Huang, Jinbo,Zhu, Qiang

supporting information, p. 4966 - 4969,4 (2012/12/12)

An unprecedented palladium-catalyzed cyanation of aromatic C-H bonds by using tertiary amine derived isocyanide as a novel cyano source was developed. Cu(TFA)2 was used as a requisite stoichiometric oxidant. Mechanistic studies suggest that a tertiary carbon cation-based intermediate is involved following the C-N bond breakage.
