Check Digit Verification of cas no

The CAS Registry Mumber 20266-12-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,6 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20266-12:
(7*2)+(6*0)+(5*2)+(4*6)+(3*6)+(2*1)+(1*2)=70
70 % 10 = 0
So 20266-12-0 is a valid CAS Registry Number.

CATALYSED LIQUID PHASE OXIDATION OF ACETALS BY MOLECULAR OXYGEN

Vcelak, Jaroslav,Klimova, Miroslava,Chvalovsky, Vaclav

, p. 847 - 866 (2007/10/02)

Nine different acetals have been oxidized in the presence of Co(OOCCH3)2*4H2O under isobaric conditions (0.1 - 0.2 MPa O2) while following the uptake of molecular oxygen.The reactivity of acetals was expressed by the rate constants of the autocatalytic model of oxidation.The main product of the oxidation are alcohols, esters and acids.The distribution of products and the total reactivity of acetals are controlled by the structure of both parts of acetal molecule.The dominant effects of the course of the reaction exerts the type of carbon atoms on which radicals are formed.The oxidation is accompanied by consecutive and co-oxidation reactions, by deactivation of the catalysts and by decarbonylation of intermediate products.The effect of oxygen pressure is reported and the more detailed radical mechanism of the oxidation is proposed.
