Check Digit Verification of cas no
The CAS Registry Mumber 671787-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,1,7,8 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 671787-01:
(8*6)+(7*7)+(6*1)+(5*7)+(4*8)+(3*7)+(2*0)+(1*1)=192
192 % 10 = 2
So 671787-01-2 is a valid CAS Registry Number.

Chang, Meng-Yang,Lin, Kuo-Ging,Chen, Shui-Tein,Chang, Nein-Chen
, p. 795 - 797 (2003)
A novel route for the synthesis of 3-toluenesulfonylglutarimides on a solid support is described. The cyclization step involves stepwise [3+3] strategy of Rink Amide resin bound onto an α-toluenesulfonyl group with various α,β-unsaturated esters.
