Check Digit Verification of cas no

The CAS Registry Mumber 67983-25-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,8 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 67983-25:
(7*6)+(6*7)+(5*9)+(4*8)+(3*3)+(2*2)+(1*5)=179
179 % 10 = 9
So 67983-25-9 is a valid CAS Registry Number.

REGIO AND STEREOSPECIFIC SYNTHESIS OF 11β-SUBSTITUTED 19-NORSTEROIDS. Influence of 11β-substitution on progesterone receptor affinity.

Belanger, A.,Philibert, D.,Teutsch, G.

, p. 361 - 382 (1981)

The convenient synthesis of a series of 11β-substituted 17-ethynyl-17β-hydroxy-4,9-estradien-3-ones and their corresponding estradiols is reported.Relative affinities for the progestin and estrogen receptors showed very specific interactions between the p
