Check Digit Verification of cas no

The CAS Registry Mumber 87753-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,7,5 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87753-42:
(7*8)+(6*7)+(5*7)+(4*5)+(3*3)+(2*4)+(1*2)=172
172 % 10 = 2
So 87753-42-2 is a valid CAS Registry Number.

Dicyclopentadiene Oxidation. II. Catalyzed Liquid-Phase Oxidation of Dicyclopentadiene

Schnurpfeil, D.

, p. 842 - 847 (2007/10/02)

The liquid-phase oxidation of dicyclopentadiene 1 by molecular oxygen was studied in the presence of MoO2(acac)2 as a typical epoxidation catalyst.The yield of the mono-epoxides 2 and 3 is increased to 56.4 percent (uncatalyzed reaction: 43.6 percent).The ratio of the two mono-epoxides is decreased to 2/3 = 2.6 in relation to the uncatalyzed reaction 2/3 = 7.1).The influence of temperature, conversion and solvents is described.The bisepoxide 4 is formed at lower conversions than in the uncatalyzed reaction.But also at higher conversion of 1 not more than 10 percent of the bisepoxide 4 is formed.
