161742-12-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 161742-12-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,7,4 and 2 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 161742-12:
(8*1)+(7*6)+(6*1)+(5*7)+(4*4)+(3*2)+(2*1)+(1*2)=117
117 % 10 = 7
So 161742-12-7 is a valid CAS Registry Number.

Palladium-catalyzed chemoselective intramolecular cyclization of 2-bromoaryl alkenenitriles

Deng, Jui-Hui,Tai, Huo-Mu,Yang, Chau-Chen

, p. 327 - 341 (2007/10/03)

The chemoselectivity in the palladium-catalyzed intramolecular cyclization of 2-(o-bromoaryl)alkenenitriles depends on the nature of α-substitutents. 2-(o-Bromoanilino)alkenenitriles attacked the cyano group, followed by the cyano group transposition and

Palladium-catalysed Regioselective Cyclisation of Unsaturated Bromoanilinoalkenenitriles

Yang, Chau-Chen,Sun, Pei-Jiun,Fang, Jim-Min

, p. 2629 - 2630 (2007/10/02)

α-(o-Bromoanilino)alkenenitriles are converted to 2-(methylamino)benzonitrile and varied γ-carbolines by catalysis with palladium; the reactions may involve intramolecular aryl additions to the cyano group and other processes such as cyano group transposi
