Check Digit Verification of cas no

The CAS Registry Mumber 152419-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,4,1 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 152419-81:
(8*1)+(7*5)+(6*2)+(5*4)+(4*1)+(3*9)+(2*8)+(1*1)=123
123 % 10 = 3
So 152419-81-3 is a valid CAS Registry Number.

BIS(4-VINYLTHIOPHENYL) BRIDGE COMPOUNDS

Nesterov, V. V.,Tarasov, A. V.,Afonin, A. V.,Moskvichev, Yu. A.,Amosova, S. V.

, p. 1526 - 1530 (2007/10/02)

Bis(vinylthiophenyl) bridge compounds were obtained for the first time by the reaction of acetylene with di(4-mercaptophenyl) ether, di(4-mercaptophenyl) sulfide, 4,4'-dimercaptobiphenyl, and bis(4-mercaptophenyl)methane in DMSO.The effect of temperature on the product yield was investigated.An alternative preparative method is proposed for the synthesis of these compounds by the dehydrochlorination of the corresponding bis(2-chloroethylthiophenyl) compounds, produced by the quantitative reaction of the dithiols with 1,2-dichloroethane.
