Check Digit Verification of cas no

The CAS Registry Mumber 1256-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,5 and 6 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1256-83:
(6*1)+(5*2)+(4*5)+(3*6)+(2*8)+(1*3)=73
73 % 10 = 3
So 1256-83-3 is a valid CAS Registry Number.

Novel Intramolecular Photorearrangement of Nitronate Anions

Yamada, Kazutoshi,Tanaka, Seiji,Naruchi, Kiyoshi,Yamamoto, Makoto

, p. 5283 - 5289 (2007/10/02)

The photochemistry of alkanenitronate anions is described.Irradiation of the alkanenitronate anions leads to hydroxamic acids by oxygen photorearrangement via ?-?* triplet excited states.The stoichiometry of reaction, anion structure and selectivity of migration, the nature of the excited state, the quantum yield of reaction, rehybridization on excitation, and the base dependency are discussed.From the results of a detailed structural study of 19 products it was found that this photorearrangement is a highly regio- and stereospecific reaction.
