Check Digit Verification of cas no

The CAS Registry Mumber 97373-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,3,7 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 97373-99:
(7*9)+(6*7)+(5*3)+(4*7)+(3*3)+(2*9)+(1*9)=184
184 % 10 = 4
So 97373-99-4 is a valid CAS Registry Number.

Effects of 16-Heterosubstitution on the Regiochemistry of the D-Homo Rearrangement

Bischofberger, Norbert,Walker, Keith A. M.

, p. 3604 - 3609 (2007/10/02)

The 16β-phenylthio-, 16β-phenylseleno-, and 16β-dimethylphenylsilyl-substituted 3β,17α-dihydroxy-5-pregnen-20-ones have been prepared by nucleophilic ring opening of 16α,17α-epoxysteroids in order to study the influence of the 16-substituent on the regioc
