Check Digit Verification of cas no

The CAS Registry Mumber 88247-65-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,2,4 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 88247-65:
(7*8)+(6*8)+(5*2)+(4*4)+(3*7)+(2*6)+(1*5)=168
168 % 10 = 8
So 88247-65-8 is a valid CAS Registry Number.

Stereoselective Synthesis of Crinosterol

Anastasia, Mario,Allevi, Pietro,Ciuffreda, Pierangela,Fiecchi, Alberto

, p. 2365 - 2367 (2007/10/02)

A stereoselective synthesis of crinosterol, (22E,24S)-ergosta-5,22-dien-3β-ol, was developed from (20S)-6β-acetoxy-3α,5-cyclo-5α-pregnane-20-carbaldehyde using the Claisen rearrangement of an appropriate precursor of established absolute configuration.
