43085-97-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 43085-97-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,8 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 43085-97:
(7*4)+(6*3)+(5*0)+(4*8)+(3*5)+(2*9)+(1*7)=118
118 % 10 = 8
So 43085-97-8 is a valid CAS Registry Number.

An effective approach to B-ring aromatization of equilin
Cao, Zhisong,Liehr, Joachim G.
, p. 145 - 155 (2007/10/03)
Epoxidation of equilin followed by rearrangement-elimination catalyzed by either proton acids or Lewis acids generates an estrogen with an aromatic B-ring. This procedure represents an effective method for the conversion of an equilin nucleus to an equilenin nucleus.
