Check Digit Verification of cas no

The CAS Registry Mumber 4278-54-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,7 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4278-54:
(6*4)+(5*2)+(4*7)+(3*8)+(2*5)+(1*4)=100
100 % 10 = 0
So 4278-54-0 is a valid CAS Registry Number.

o-Quinone methide based approach to isoflavans: application to the total syntheses of equol, 3′-hydroxyequol and vestitol

Gharpure, Santosh J.,Sathiyanarayanan,Jonnalagadda, Prasad

, p. 2974 - 2978 (2008/09/20)

A concise strategy is developed for the synthesis of isoflavans employing a Diels-Alder reaction between o-quinone methides and aryl-substituted enol ethers followed by reductive cleavage of the acetal group. The method is extended towards the total syntheses of equol, 3′-hydroxyequol and vestitol.
