Check Digit Verification of cas no

The CAS Registry Mumber 7630-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,3 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7630-21:
(6*7)+(5*6)+(4*3)+(3*0)+(2*2)+(1*1)=89
89 % 10 = 9
So 7630-21-9 is a valid CAS Registry Number.

1H-tetrazole selectively catalyzed mono addition of alcohols to phosphonic dichlorides such that mixed phosphonate diesters could be synthesized in high yields and under mild conditions.

SILICON-PHOSPHORUS ANALOGIES. NUCLEOPHILIC CATALYSIS IN THE ALCOHOLYSIS OF CHLOROPHOSPHORUS DERIVATIVES

Corriu, Robert J. P.,Lanneau, Gerard F.,Leclercq, Dominique

, p. 1959 - 1974 (2007/10/02)

The mechanism of the alcoholysis of chlorophosphonates and chlorophosphates in presence of nucleophilic catalysts like hexamethylphosphotriamide, pyridine and N-methylimidazole is discussed on the basis of kinetic and stereochemical results.We have proposed a mechanism for the reaction, which is governed by entropy, involving reaction of the alcohol with a pentacoordinated intermediate.This accounts for the differences in the stereochemical outcome and the rate equation which can be derived for the reaction with a variety of substrates in addition to the absence of common ion + solvent effects observed.
