Check Digit Verification of cas no

The CAS Registry Mumber 651-55-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 651-55:
(5*6)+(4*5)+(3*1)+(2*5)+(1*5)=68
68 % 10 = 8
So 651-55-8 is a valid CAS Registry Number.

B-ring aromatization of estrogen derivatives

Hylarides,Wilbur,Mettler Jr.

, p. 657 - 662 (2007/10/02)

A noval method of B-ring aromatization of steroid derivatives is reported. Addition of BrCl in methanol to a non-aromatic B-ring double bond results in a rapid double elimination generating the aromatic B-ring. This procedure represents an effective method for conversion of an equilin to an equilenin nucleus.
