Check Digit Verification of cas no
The CAS Registry Mumber 77943-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 77943-98:
(7*7)+(6*7)+(5*9)+(4*4)+(3*3)+(2*9)+(1*8)=187
187 % 10 = 7
So 77943-98-7 is a valid CAS Registry Number.

18-Substituted Steroids. Part 8. An Improved Synthesis of 11β,18,21-Trihydroxypregn-4-ene-3,20-dione ('18-Hydroxycorticosterone')
Kirk, David N.,Slade, Christopher J.
, p. 703 - 705 (2007/10/02)
'18-Hydroxycorticosterone' (1) has been prepared from 11β-formyloxy-20-hydroxypregn-4-en-3-one (6) by application of the 'hypoiodite' series of reactions , followed by acetoxylation at C-21 by lead tetra-acetate in acetic acid.Alkaline hydrolysis then gave 18-hydroxycorticosterone.
