Check Digit Verification of cas no

The CAS Registry Mumber 50423-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,4,2 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 50423-77:
(7*5)+(6*0)+(5*4)+(4*2)+(3*3)+(2*7)+(1*7)=93
93 % 10 = 3
So 50423-77-3 is a valid CAS Registry Number.

THE OXIDATIVE TRANSFORMATIONS OF (+)CATECHIN AND (-)EPICATECHIN AS STUDIED BY ESR. FORMATION OF HYDROXYCATECHINIC ACIDS.

Jensen, Ove N.,Pedersen, Jens A.

, p. 1609 - 1616 (1983)

The alkaline air oxidation of (+)catechin and (-)epicatechin has been studied by ESR spectroscopy.Both compounds give rise to the anion radicals of 2'-hydroxycatechinic acid and 6'-hydroxycatechinic acid by way of a hydroxylation and a rearrangement reaction.The primary spectra of (+)catechin, catechinic acid and the intermediate radicals of 2'-hydroxy-(+)catechin and 6'-hydroxy-(+)catechin are observed and characterized by ESR.
