Check Digit Verification of cas no

The CAS Registry Mumber 76461-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,6 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76461-37:
(7*7)+(6*6)+(5*4)+(4*6)+(3*1)+(2*3)+(1*7)=145
145 % 10 = 5
So 76461-37-5 is a valid CAS Registry Number.

EPOXIDATION OF RETINOL AND THE STRUCTURE OF "CHROMOGEN 574"

Welch, Steven C.,Gruber, John M.,Rao, Prakasa A. S. C.

, p. 1179 - 1182 (1980)

Epoxidation of retinol (vitamin A alcohol, 1) with freshly prepared and standardized mono-perphtalic acid in ether affords a product which Karrer named "chromogen 574" in 1945.Repetition of this peracid oxidation of retinol (1) with several peracids (m-PPA, m-CPBA, or CH3CO3H) with or without a buffer (NaHCO3 or Na2HPO4) produces dihydropyran alcohol 4 as characterised by spectroscopy and subsequent chemical transformations.Thus the structures proposed for "chromogen 574" by Karrer in 1945-47 and Troitskii in 1948 are now revised to correspond to cyclic alkohol 4.
