Check Digit Verification of cas no

The CAS Registry Mumber 2102-31-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,0 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2102-31:
(6*2)+(5*1)+(4*0)+(3*2)+(2*3)+(1*1)=30
30 % 10 = 0
So 2102-31-0 is a valid CAS Registry Number.

STEREOCHIMIE-LVII ETUDE STEREOCHIMIQUE ET CINETIQUE DE LA BROMATION D'ESTERS ET D'ETHERS ENOLIQUES STEROIDIQUES

Calvet, Alain,Jozefowitz, Marcel,Levisalles, Jacques

, p. 103 - 115 (2007/10/02)

Absolute rates of bromination were measured for two series of derivatives of steroidal ketones 3, enol acetates 1 and enol methyl ether 2.Axial substituents exhibited a large effect on rates, which increased by 15,000 fold on going from (X=CH3; Y=CN) to (X=Y=H).From the bromide ion effect it was concluded that the first step (formation of an intermediate bromonium ion) was reversible and that the second step (formation of haloketones 4 or 5 or of haloacetals 8 or 9) was slow compared to the first step.The intermediate was concluded to be a highly unsymmetrical bromonium ion rather than a plain oxocarbenium ion.
