Check Digit Verification of cas no

The CAS Registry Mumber 133846-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,4 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 133846-72:
(8*1)+(7*3)+(6*3)+(5*8)+(4*4)+(3*6)+(2*7)+(1*2)=137
137 % 10 = 7
So 133846-72-7 is a valid CAS Registry Number.

Carbanion addition to acetylenes: An efficient stereoselective route to α-methylene-γ-lactams

Patra,Maiti,Chatterjee,Chakravarty

, p. 1363 - 1366 (1991)

Intramolecular addition of carbanions, derived from the acetylenic amides (5b,d), (7) and (9) has been shown to be highly stereoselective leading to the α-methylene-γ-lactam derivatives (6a,b), (8a,b) and (10).
