Check Digit Verification of cas no

The CAS Registry Mumber 176513-36-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,6,5,1 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 176513-36:
(8*1)+(7*7)+(6*6)+(5*5)+(4*1)+(3*3)+(2*3)+(1*6)=143
143 % 10 = 3
So 176513-36-3 is a valid CAS Registry Number.

Ring expansion of norpenicillin to 3-norcephalosporin

Van Der Klein, Pieter A. M.,Castelijns, Judith,Hirs, Hans G. J.,Verweij, Jan,De Vroom, Erik

, p. 185 - 190 (2007/10/03)

The Morin ring expansion of penicillin 1-oxides to cephalosporins has been extended to norpenicillin 1-oxides. To this end, both the norpenicillin sulfoxide moiety and the methyl group should be β-oriented. Norpenicillin 1-oxides are prepared from properly protected exomethylene penam derivatives using hydrogen on palladium/carbon and oxidation with 3-chloroperoxybenzoic acid or peroxyacetic acid.
