Check Digit Verification of cas no

The CAS Registry Mumber 128989-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128989-59:
(8*1)+(7*2)+(6*8)+(5*9)+(4*8)+(3*9)+(2*5)+(1*9)=193
193 % 10 = 3
So 128989-59-3 is a valid CAS Registry Number.

N-vinyl and N-unsubstituted β-lactams from 1-substituted 2-aza-1,3-butadienes

Georg,He,Kant,Mudd

, p. 451 - 454 (1990)

The reaction of acid chlorides and N-vinyl imines results in the stereoselective formation of cis N-vinyl β-lactams. The N-vinyl protecting group can be removed either oxidatively or hydrolytically to yield N-substituted β-lactams.
