Check Digit Verification of cas no

The CAS Registry Mumber 117516-54-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,1 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117516-54:
(8*1)+(7*1)+(6*7)+(5*5)+(4*1)+(3*6)+(2*5)+(1*4)=118
118 % 10 = 8
So 117516-54-8 is a valid CAS Registry Number.

Thermolysis of 4-(ω-hydroxyalkyl)-2,6-di-tert-butylphenols

Krysin,Egorova,Vasil'Ev

, p. 275 - 283 (2010)

The process of thermolysis of tert-butylated hydroxyalkyl phenols includes de-tert-butylation, etherification, and fragmentation of the hydroxyalkyl group. On the basis of the proposed schemes of the mechanism of thermal de-tert-butylation the path of the search for catalysts for the synthesis of 4-hydroxyalkylphenols is defined and transformations of the by-products into biologically active substances were considered.
