Calculate Digit Verification of CAS Registry Number 196881-38:
(8*1)+(7*9)+(6*6)+(5*8)+(4*8)+(3*1)+(2*3)+(1*8)=196
196 % 10 = 6
So 196881-38-6 is a valid CAS Registry Number.

11,21-Bisphenyl-19-norpregnane derivatives are selective antiglucocorticoids

Gebhard,Van Der Voort,Schuts,Schoonen

, p. 2229 - 2234 (2007/10/03)

An efficient eight-step synthesis of 11,21-bisphenyl-19-norpregnane derivatives (10) starting from 19-norandrosta-4,9-diene-3,17-dione (5) is described. It is shown that specific combinations of polar substitutions on the 11- and the 21-phenylring in compounds (10) lead to selective antiglucocorticoids with relative high binding to the glucocorticoid receptor and almost negligible binding to the progesterone receptor.
