Check Digit Verification of cas no

The CAS Registry Mumber 138019-00-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,1 and 9 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138019-00:
(8*1)+(7*3)+(6*8)+(5*0)+(4*1)+(3*9)+(2*0)+(1*0)=108
108 % 10 = 8
So 138019-00-8 is a valid CAS Registry Number.

A convenient and highly stereoselective synthesis of 4α-deuterio and -tritio steroids catalyzed by Pd

Rabinowitz

, p. 6081 - 6084 (1991)

A simple and highly stereoselective synthesis of [4α-2H]- and [4α-3H]-Δ5-3β-hydroxysteroids is presented. Palladium(O)-mediated borodeuteride reduction of readily-available cholest-5-en-3β,4β-diol cyclic carbonate provides [4α-2H]-Δ5-and Δ4-cholesterol in a 12:1 ratio. Reduction of [4α-3H]-cholest-5-ene-3β,4β-diol cyclic carbonate with NaB1H4 and Pd(O) resulted in [4β-3H]-cholesterol.
