Check Digit Verification of cas no

The CAS Registry Mumber 104203-06-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,0 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104203-06:
(8*1)+(7*0)+(6*4)+(5*2)+(4*0)+(3*3)+(2*0)+(1*6)=57
57 % 10 = 7
So 104203-06-7 is a valid CAS Registry Number.

New Synthesis of the Corticosterone Side-Chain

Solyom, Sandor,Szilagyi, Katalin,Toldy, Lajos

, p. 153 - 160 (2007/10/02)

Condensation reactions between azlactone 2 and 17-ketosteroids 1 followed by opening of the azlactone ring with sodium methanolate yields methyl 20-benzoylamino-17(20)-pregnen-21-oates 6.Reduction of the ester and subsequent hydrolysis produce compounds with the corticosterone side-chain as well as a ring-closed product of new type.
