Check Digit Verification of cas no

The CAS Registry Mumber 1617519-65-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,7,5,1 and 9 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1617519-65:
(9*1)+(8*6)+(7*1)+(6*7)+(5*5)+(4*1)+(3*9)+(2*6)+(1*5)=179
179 % 10 = 9
So 1617519-65-9 is a valid CAS Registry Number.

Preparation of fused β-lactams through Weinreb amide α-anions

Hewitt, William M.,Egger, Michael,Zuckerman, Nathaniel B.,Konopelski, Joseph P.

, p. 5283 - 5290 (2014/07/08)

Enantiomerically pure β-lactams bearing a Weinreb amide functionality at the C3 position have been shown to be excellent substrates for α-alkylation reactions, generating C3 quaternary centers with predictable absolute stereochemistry. In addition, oxidative coupling of C3/C4 dianions affords entry to fused β,γ-bislactam systems.
