Check Digit Verification of cas no

The CAS Registry Mumber 94983-95-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,9,8 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 94983-95:
(7*9)+(6*4)+(5*9)+(4*8)+(3*3)+(2*9)+(1*5)=196
196 % 10 = 6
So 94983-95-6 is a valid CAS Registry Number.

Diozonolyses of Acyclic Conjugated Dienes in Methanol

Griesbaum, Karl,Zwick, Gerhard

, p. 229 - 243 (2007/10/02)

In the diozonolyses of isoprene (1a), 2-methyl-3-phenyl-1,3-butadiene (1b), 2,3-diphenyl-1,3-butadiene (26), and 2,3,4,5-tetramethyl-2,4-hexadiene (30) in methanol subsequent reactions of the primary cleavage products afforded abnormal products, which arose from cleavage of both the double bonds and the single bonds of the diene systems.In addition, the diozonolyses of 26 and 30 gave products, in which one of the double bonds of the respective diene system has been epoxidized.The mode of formation of the abnormal cleavage products has been elucidated by the ozonolysis of the intermediate products, viz. of α,β-unsaturated methoxyhydroperoxides and of α,β-unsaturated carbonyl compounds.
