Check Digit Verification of cas no

The CAS Registry Mumber 129441-77-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 129441-77:
(8*1)+(7*2)+(6*9)+(5*4)+(4*4)+(3*1)+(2*7)+(1*7)=136
136 % 10 = 6
So 129441-77-6 is a valid CAS Registry Number.

UNEXPECTED REACTION BETWEEN DCC AND CEPHALOSPORANIC ACID SULPHONES

Alpegiani, Marco,Bissolino, Pierluigi,Arlandini, Emanuele,Borghi, Daniela,Perrone, Ettore

, p. 139 - 147 (2007/10/02)

Cephalosporanic acid sulphones react with DCC to give a novel 4-spiroazetidinyl-Δ2-cephem structure with high stereoselectivity.The reaction, though general for cephem-4-carboxylic acids, is deeply affected by oxidation at sulphur; an external
