Check Digit Verification of cas no

The CAS Registry Mumber 902141-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,1,4 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 902141-04:
(8*9)+(7*0)+(6*2)+(5*1)+(4*4)+(3*1)+(2*0)+(1*4)=112
112 % 10 = 2
So 902141-04-2 is a valid CAS Registry Number.

Synthesis of (3S)-hydroxyandrosta-5,7-diene-17-ones via intramolecular cobalt-mediated [2+2+2] cycloaddition

Groth, Ulrich,Richter, Norbert,Kalogerakis, Aris

, p. 905 - 908 (2007/10/03)

A new method for the synthesis of lumisterin-type steroids following the D→ABCD approach is reported. A key step is the cobalt-induced cyclization of a cyclopentanoid enediyne, which was prepared via thioalkylation of the zinc enolate of a 2,3-substituted
