Check Digit Verification of cas no
The CAS Registry Mumber 3563-27-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,6 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3563-27:
(6*3)+(5*5)+(4*6)+(3*3)+(2*2)+(1*7)=87
87 % 10 = 7
So 3563-27-7 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.
