The CAS Registry Mumber 81983-26-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,8 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 81983-26:
(7*8)+(6*1)+(5*9)+(4*8)+(3*3)+(2*2)+(1*6)=158
158 % 10 = 8
So 81983-26-8 is a valid CAS Registry Number.

Synthesis of 11α-hydroxyprogesterone haptens

Yoshida, Hirokazu,Nakai, Shiro,Nimbari, Fusako,Yoshimoto, Kiyoko,Nishimura, Tadashi

, p. 727 - 738 (1989)

C-4 and C-6 bridged haptens of 11α-hydroxyprogesterone, an anti-androgen, were respectively synthesized via 4,5 and 5α,6α epoxide ring openings using 3-mercaptopropanoic acid.Substitution of 6-bromo derivative of progesterone using the same reagent unexpectedly afforded a C-4 substituted product instead of the normal C-6 substituted product previously reported in the literature.
