Check Digit Verification of cas no
The CAS Registry Mumber 138548-82-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,4 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138548-82:
(8*1)+(7*3)+(6*8)+(5*5)+(4*4)+(3*8)+(2*8)+(1*2)=160
160 % 10 = 0
So 138548-82-0 is a valid CAS Registry Number.

A-ring aromatic 9,10-secosteroids by radical-induced fragmentation of 3-oxo-1,4-diene derivatives
Kunzer,Sauer,Wiechert
, p. 7247 - 7250 (1991)
For nine steroid representatives in the 3-oxo-1,4-diene series, the majority of which bears a methyl substituent at C(1), it is shown that both tri-n-butyltin hydride and tris(trimethylsilyl)silane promote C(9)-C(10) bond cleavage in the presence of a rad
