Check Digit Verification of cas no
The CAS Registry Mumber 13742-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,4 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13742-19:
(7*1)+(6*3)+(5*7)+(4*4)+(3*2)+(2*1)+(1*9)=93
93 % 10 = 3
So 13742-19-3 is a valid CAS Registry Number.

SUBSTITUTED 7,7',8,8'-TETRACYANOQUINODIMETHANES. I. METHODS OF SYNTHESIS OF SUBSTITUTED 7,7',8,8'-TETRACYANOQUINODIMETHANES

, p. 742 - 745 (2007/10/02)
The synthesis of 2-methyl-, 2,5-dimethyl-, and 2-isopropyl-7,7'-8,8'-tetracyanoquinodimethanes was realized from 2-methyl-, 2,5-dimethyl-, and 2-isopropyl-1,4-cyclohexanediones.These cyclic diketones are obtained with good yields by the Birch reduction of 2-chloromethyl-, 2,5-dichloromethyl-, and 2-isopropyl-1,4-dimethoxybenzenes.
