Check Digit Verification of cas no

The CAS Registry Mumber 140844-33-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,8,4 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 140844-33:
(8*1)+(7*4)+(6*0)+(5*8)+(4*4)+(3*4)+(2*3)+(1*3)=113
113 % 10 = 3
So 140844-33-3 is a valid CAS Registry Number.

THE STEREOCONTROLLED SYNTHESIS OF VERSATILE CARBAPENEM INTERMEDIATES USING THE BARTON O-ACYL 2-THIOPYRIDYLHYDROXAMATE FRAGMENTATION

Sumi, Kenzo,Fabio, Romani Di,Hanessian, Stephen

, p. 749 - 752 (1992)

The photo-initiated fragmentation of 2-azetidinone-4-carboxylic acid 2-thiopyridylhydroxamates (Barton reaction) in the presence of Michael acceptors leads to the introduction of a doubly functionalized carbon chain, useful for the elaboration of carbapenem and related β-lactam antibiotics.
