Check Digit Verification of cas no

The CAS Registry Mumber 77198-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 77198-31:
(7*7)+(6*7)+(5*1)+(4*9)+(3*8)+(2*3)+(1*1)=163
163 % 10 = 3
So 77198-31-3 is a valid CAS Registry Number.

An improved and clean procedure for the synthesis of one-donor poly-acceptors systems containing 2,6-dicyanoamine moiety in aqueous media catalyzed by TEBAC in the presence and absence of K2CO3

Wang, Xiang-Shan,Zhang, Mei-Mei,Li, Qing,Yao, Chang-Sheng,Tu, Shu-Jiang

, p. 5265 - 5273 (2007)

A clean and simple synthesis of one-donor poly-acceptors systems containing 2,6-dicyanoamine moiety was accomplished via the reaction of 1-arylethylidenemalonodinitriles with arylidenemalonodinitriles in aqueous media catalyzed by TEBAC in the presence of

CYCLIZATION REACTIONS OF NITRILES. III. SYNTHESIS OF o-CYANOANILINES BY THE THORPE REACTION

Sharanin, Yu. A.,Baskakov, Yu. A.,Abramenko, Yu. T.,Putsykin, Yu. G.,Vasil'ev, A. F.,Nazarova, E.B.

, p. 1870 - 1879 (2007/10/02)

The reaction of alkylidenemalononitriles with arylidene derivatives of malononitrile and cyanoacetic ester leads to the formation of derivatives of 1-amino-2,6-dicyano-3,5-diaryl-1,3-cyclohexadiene or 2,4-dicyano-3-amino-5-arylbicyclodeca-2,10-dien
