Check Digit Verification of cas no

The CAS Registry Mumber 1189062-32-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,0,6 and 2 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1189062-32:
(9*1)+(8*1)+(7*8)+(6*9)+(5*0)+(4*6)+(3*2)+(2*3)+(1*2)=165
165 % 10 = 5
So 1189062-32-5 is a valid CAS Registry Number.

Enantioselective synthesis of Aza-β-lactams via NHC-catalyzed [2 + 2] cycloaddition of ketenes with diazenedicarboxylates

Huang, Xue-Liang,Chen, Xiang-Yu,Ye, Song

supporting information; experimental part, p. 7585 - 7587 (2010/01/06)

(Chemical Equation Presented) N-Heterocyclic carbenes were found to be efficient catalysts for the formal [2 + 2] cycloaddition of aryl-(alkyl)ketenes and diazenedicarboxylates to give the corresponding aza-β-lactams in good yields with up to 91% ee. The
