Check Digit Verification of cas no

The CAS Registry Mumber 118002-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 118002-19:
(8*1)+(7*1)+(6*8)+(5*0)+(4*0)+(3*2)+(2*1)+(1*9)=80
80 % 10 = 0
So 118002-19-0 is a valid CAS Registry Number.

STEROIDS. LIV. SYNTHESIS OF 17β-AMINO-5α-ANDROSTAN-3α-OL FROM EPIANDROSTERONE

Nadaraia, N. Sh.,Sladkov, V. I.,Suvorov, N. N.

, p. 682 - 686 (2007/10/02)

17β-Amino-3α-hydroxy-5α-androstane was synthesized from epiandrosterone by: a) epimerization at C3 by the Luttrell-Lochaus method to androsterone followed by reductive amination; b) Leuckart-Wallach amination followed by epimerization of the 3β-hydroxy-17β-formamido-5α-androstane at C3 by the Mitsunobu method.
