199471-98-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199471-98-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,4,7 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 199471-98:
(8*1)+(7*9)+(6*9)+(5*4)+(4*7)+(3*1)+(2*9)+(1*8)=202
202 % 10 = 2
So 199471-98-2 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
