Check Digit Verification of cas no

The CAS Registry Mumber 97580-20-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,8 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 97580-20:
(7*9)+(6*7)+(5*5)+(4*8)+(3*0)+(2*2)+(1*0)=166
166 % 10 = 6
So 97580-20-6 is a valid CAS Registry Number.

α-HYDROXYALKYLATION OF HETEROAROMATIC BASES BY ALCOHOLS AND HYDROXYLAMINE-O-SULPHONIC ACID

Citterio, Attilio,Gentile, Anna,Minisci, Francesco,Serravalle, Marco,Ventura, Susanna

, p. 617 - 620 (1985)

The homolytic decomposition of hydroxylamine-O-sulphonic acid in alcoholic solvents was investigated in the presence or absence of protonated heteroaromatic bases and Fe(II) salt.THe addition of the α-hydroxyalkyl radicals to the base and their oxidation by Fe(III) salt to the corresponding alkyl cyanide were competitive processes.A redox chain process involving the amino radical cation NH3+, is suggested and the factors affecting the yields of the homolytic substitution are discussed.
