81522-52-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81522-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81522-52:
(7*8)+(6*1)+(5*5)+(4*2)+(3*2)+(2*5)+(1*2)=113
113 % 10 = 3
So 81522-52-3 is a valid CAS Registry Number.

Chemistry of Diazoacenaphthenones and Diazoacenaphthenes

Chang, S.-J.,Shankar, B. K. Ravi,Shechter, H.

, p. 4226 - 4234 (1982)

Wolff rearrangements do not occur in photolyses or thermolyses of diazoacenaphthenone (1), 2-diazo-5-nitroacenaphthenone (2), and 2-diazoaceanthrenone (3) in various environments.Thermal and photochemical decompositions of 1 in cyclooctane result in loss of nitrogen and formation of 2-cyclooctylacenaphthenone (29).In 2-propanol containing oxygen, 1 converts photolytically to acenaphthenone (22), acetone (23), and 1,8-naphthalic anhydride (25).Irradiation of 1 in tert-butyl alcohol/oxygen yields 2-tert-butoxyacenaphthenone (28) by solvent capture along with 25.Diazoketones 1-3 do not effect photochemical cyclopropanation of simple olefins; electronegatively substituted olefins such as acrylonitrile and methyl acrylate do give spirocyclopropanes however.Oxazoles are formed by 1,3-dipolar reactions of 1-3 with nitriles with loss of nitrogen.Acetylenes also react photolytically with 1-3 with nitrogen expulsion to yield furanes regiospecifically.Thermolyses of 1-3 in acetylenes, however, result in initial 1,3-dipolar addition reactions to give spiropyrazoles which undergo spotaneous sigmatropic migrations of their carbonyl groups to nitrogen to form isoquinolines.Diazoacenaphthene (13) decomposes carbenically to acenaphthylene (66).Similarly, 2-diazo-1,1-dimethylacenaphthene (14) converts to 8-methylcyclopropacenaphthylene (66) which then isomerizes thermally to methylphenalenes (70a-d).Further, 2-diazoacenaphthenone ethylene acetal (17) thermolyzes and photolyzes with migration of one of its acetal oxygen moieties to yield 8,9-dihydroacenaphtho-p-dioxin (73).Ring contraction does not occur in carbenic decompositions of 13, 14, and 17.
