Check Digit Verification of cas no

The CAS Registry Mumber 144602-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,6,0 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144602-48:
(8*1)+(7*4)+(6*4)+(5*6)+(4*0)+(3*2)+(2*4)+(1*8)=112
112 % 10 = 2
So 144602-48-2 is a valid CAS Registry Number.

A CONVENIENT ACCESS TO 16-METHYLENE AND 16β-METHYL CORTICOSTEROIDS BY A NOVEL TRANSFORMATION OF GEMINAL BIS(PHENYLSULPHINYL) INTERMEDIATES

Boivin, Jean,Chauvet, Christine,Zard, Samir Z.

, p. 4913 - 4916 (2007/10/02)

16α-Bis(phenylsulphinyl) methyl pregnane derivative 7 gives, by a series of eliminations and rearrangements, the corresponding 16-methylene intermediate 4 on heating in the presence of triphenylphosphine.Regio- and stereoselective hydrogenation of the latter using Wilkinson's catalyst furnishes 16β-methyl corticosteroid 5.
