Check Digit Verification of cas no
The CAS Registry Mumber 17652-16-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,5 and 2 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17652-16:
(7*1)+(6*7)+(5*6)+(4*5)+(3*2)+(2*1)+(1*6)=113
113 % 10 = 3
So 17652-16-3 is a valid CAS Registry Number.

Microbial hydroxylation of steroids. 10. Rearrangement during epoxidation and hydroxylation, and the stepwise nature of these enzymic reactions
Holland, Herbert L.,Riemland, Elly
, p. 1121 - 1126 (2007/10/02)
A series of unsaturated steroids has been incubated with fungi which are known to hydroxylate at a site corresponding to the allylic position in the analogous saturated steroids.In some cases, the anticipated hydroxylation occurred without rearrangement of the double bond.In a number of instances, however, products were obtained whose structures implied that allylic rearrangement had occurred during the reaction.The formation of these products is consistent with a stepwise mechanism of enzymatic oxidation.Possible routes for product formation are presented which incorporate this proposal.
