Check Digit Verification of cas no

The CAS Registry Mumber 1417728-64-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,7,7,2 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1417728-64:
(9*1)+(8*4)+(7*1)+(6*7)+(5*7)+(4*2)+(3*8)+(2*6)+(1*4)=173
173 % 10 = 3
So 1417728-64-3 is a valid CAS Registry Number.

Study of the O-glycidylation of natural phenolic compounds. the relationship between the phenolic structure and the reaction mechanism

Aouf, Chahinez,Le Guernevé, Christine,Caillol, Sylvain,Fulcrand, Hélène

, p. 1345 - 1353 (2013/02/23)

The O-alkylation reaction by epichlorohydrin of some natural phenolic compounds such as 4-methylcatechol, gallic acid, protocatechuic acid, pyrogallol and resorcinol was investigated. Phenolic compounds reacted first with epichlorohydrin in the presence of benzyltriethylammonium chloride as phase transfer catalyst. Then, an aqueous solution of sodium hydroxide was added. It was demonstrated that the two competitive mechanisms involved in the O-alkylation reaction were highly dependent of the starting material. The O-alkylated products obtained in this reaction could be further used as bisphenol A substitutes in the synthesis of epoxy resins pre-polymers.
