Check Digit Verification of cas no
The CAS Registry Mumber 113656-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,6,5 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 113656-08:
(8*1)+(7*1)+(6*3)+(5*6)+(4*5)+(3*6)+(2*0)+(1*8)=109
109 % 10 = 9
So 113656-08-9 is a valid CAS Registry Number.

ADDITION OF PENICILLIN GRIGNARDS TO GLYOXALS A SYNTHESIS OF NOVEL PENAM KETOALCOHOLS
Reed, Larry A. III,Charleson, Dan A.,Volkmann, Robert A.
, p. 3431 - 3434 (2007/10/02)
The condensation of penicillin Grignards with substituted glyoxals leads to the synthesis of novel penam α-ketoalcohol antibacterials which are structurally related to several clinically useful penicillins.
