127526-86-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127526-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,2 and 6 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 127526-86:
(8*1)+(7*2)+(6*7)+(5*5)+(4*2)+(3*6)+(2*8)+(1*6)=137
137 % 10 = 7
So 127526-86-7 is a valid CAS Registry Number.

Reaction of N-Acyloxy-2-nitrobenzenamines.I. Thermolysis in Benzene or Bromobenzene

Bryant, Ian R.,Dyall, Leonard K.

, p. 2275 - 2288 (2007/10/02)

N-Acyloxy-2-nitro- and N-acyloxy-2,4-dinitro-benzenamines have been pyrolysed at 140 deg C in benzene or bromobenzene solution.Homolysis ( to form RCO2-radical and ArNH-radical) is ruled out since virtually all the carboxylate is isolated as carboxylic acid.This acid might arise via a concerted elimination process ( the other product being a benzofurazan 1-oxide), or via heterolysis to ArNH01+, RCO21- with subsequent transfer of proton, and cyclization of the singlet 2-nitrophenylnitrene.These simple reactions compete with bimolecular reactions of products with substrate, in which the corresponding amine, azoxy compound and acid anhydride are generated.Attempts to synthesize N-tosyloxy derivatives of nitrobenzenamines gave only thermal decomposition products.N-Trifluoroacetoxy-2,4-dinitrobenzenamine was isolated as a crude product which detonated violently.
