Check Digit Verification of cas no
The CAS Registry Mumber 26789-44-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,8 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 26789-44:
(7*2)+(6*6)+(5*7)+(4*8)+(3*9)+(2*4)+(1*4)=156
156 % 10 = 6
So 26789-44-6 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.
