26819-57-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26819-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,1 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26819-57:
(7*2)+(6*6)+(5*8)+(4*1)+(3*9)+(2*5)+(1*7)=138
138 % 10 = 8
So 26819-57-8 is a valid CAS Registry Number.

1-ACETOXY-2-CYCLOHEXENE OXIDATION IN THE PRESENCE OF MOLYBDENUM, VANADIUM AND CHROMIUM COMPOUNDS

Bandurko, Valentina,Gudimenko, Yurii,Shingel, Igor,Agabekov, Vladimir,Mitskevich, Nikolai

, p. 173 - 184 (2007/10/02)

A study has been made on the catalytic oxidation of ACH-2 with molecular oxygen.The composition of reaction products (1-acetoxy-2-cyclohexene-4-one, 1-acetoxy-2-cyclohexene-4-ol) and their formation pathway have been analyzed.In MoO2(acac)2 catalysis, 1-acetoxy-2,3-epoxycyclohexane is formed. In an ACH-2 medium, the catalytic HP-decomposition mechanism and reaction yields have been investigated.The HP-decomposition have been shown to proceed through intermediate complexes over catalysts with the following overall decomposition rate constants: The hydroperoxide decomposes mainly heterolytically in the presence of MoO2(acac)2.With Cr(acac)2 the radical decomposition fraction amounts to under 1percent.
