Check Digit Verification of cas no

The CAS Registry Mumber 128023-39-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,0,2 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128023-39:
(8*1)+(7*2)+(6*8)+(5*0)+(4*2)+(3*3)+(2*3)+(1*9)=102
102 % 10 = 2
So 128023-39-2 is a valid CAS Registry Number.

A Annulation Approach to Nitrogen Heterocycles Using 2,3-Bis(phenylsulfonyl)-1,3-butadiene and Primary Amines

Padwa, Albert,Norman, Byran H.

, p. 4801 - 4807 (2007/10/02)

The reaction of amines with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords pyrrolidines in high yield.The formation of nitrogen heterocycle involves initial conjugate addition and this is followed by a 5-endo-trig cyclization of the resulting amine onto th
