Check Digit Verification of cas no

The CAS Registry Mumber 129976-61-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,9,7 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 129976-61:
(8*1)+(7*2)+(6*9)+(5*9)+(4*7)+(3*6)+(2*6)+(1*1)=180
180 % 10 = 0
So 129976-61-0 is a valid CAS Registry Number.

Ozonolsysis of 1,4-disubstituted 1,3-cyclohexadienes and of related compounds in methanol

Griesbaum, Karl,Mertens, Henri,Jung, In Chang

, p. 1369 - 1375 (2007/10/02)

Ozonolysis of 1,4-dimethyl- (5a) and 1-methyl-4-isopropyl-1,3-cyclohexadiene (5b) in methanol occur stepwise by sequential cleavage of the two double bonds.Monoozonolysis products are the corresponding compounds 6 and 7, and diozonolysis products are the corresponding cyclic peroxides 19, 20, and 21.By contrast, ozonolysis of the non-conjugated diene 2,5-dimethyl-1,5-hexadiene (13) in methanol occurs by simultaneous mono- and diozonolysis to give 14, 16a, 18a, and 20a.
