263395-57-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 263395-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,3,3,9 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 263395-57:
(8*2)+(7*6)+(6*3)+(5*3)+(4*9)+(3*5)+(2*5)+(1*7)=159
159 % 10 = 9
So 263395-57-9 is a valid CAS Registry Number.

New highly stereoselective synthesis of (E)-droloxifene via selective protection of 3,4'-dihydroxybenzophenone and McMurry reaction

Gauthier, Sylvain,Sancéau, Jean-Yves,Mailhot, Josée,Caron, Brigitte,Cloutier, Julie

, p. 703 - 709 (2007/10/03)

A new, highly stereoselective synthesis of (E)-droloxifene is reported. Deprotection of 3,4'-dimethoxybenzophenone and selective pivaloylation of the 3'-phenolic position gave 4-hydroxy-3'-(trimethylacetoxy)benzophenone. A McMurry reaction between the preceding benzophenone and propiophenone gave the (E)-olefin as a major product (14:1 E/Z ratio in crude reaction), which was then alkylated with 2-dimethylaminoethyl chloride and deprotected to yield (E)-droloxifene with a > 100:1 E/Z ratio (5 steps, 13%). Attempts to use this strategy as a suitable stereoselective method to obtain (Z)- droloxifene were not successful. (C) 2000 Elsevier Science Ltd.
