Check Digit Verification of cas no

The CAS Registry Mumber 51552-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,5 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51552-27:
(7*5)+(6*1)+(5*5)+(4*5)+(3*2)+(2*2)+(1*7)=103
103 % 10 = 3
So 51552-27-3 is a valid CAS Registry Number.

Chemoselective lactam formation in the addition of benzenesulfonyl bromide to N-allyl acrylamides and N-allyl 3,3-dimethylacrylamides

Wang,Russell

, p. 2346 - 2352 (1999)

Chemoselectivity in the addition and cyclization reactions of PhSO2Br to N-allyl acrylamides has been confirmed due to the higher reactivity of the acrylic C=C bond toward the sulfonyl radical than that of the allyl C=C bond. Formation of γ-lactams by C(β)→C(α) cyclization can be achieved with N- allyl 3,3-dimethylacrylamides.
