Check Digit Verification of cas no

The CAS Registry Mumber 137167-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,1,6 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137167-58:
(8*1)+(7*3)+(6*7)+(5*1)+(4*6)+(3*7)+(2*5)+(1*8)=139
139 % 10 = 9
So 137167-58-9 is a valid CAS Registry Number.

Nucleophilic substitution of 3-fluorosulfonyloxy cephalosporins with organocuprates

Roth, Gregory P.,Peterson, Scott A.,Kant, Joydeep

, p. 7229 - 7230 (2007/10/02)

3-Fluorosulfonyloxy cephems readily undergo addition-elimination reactions with organocuprates derived from the corresponding Grignard reagents. This chemistry presents an efficient, cost effective process for the preparation of 3-substituted cephems.
