Check Digit Verification of cas no

The CAS Registry Mumber 72997-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,9,9 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72997-93:
(7*7)+(6*2)+(5*9)+(4*9)+(3*7)+(2*9)+(1*3)=184
184 % 10 = 4
So 72997-93-4 is a valid CAS Registry Number.

Synthesis of aziridines by electrochemical oxidative annulation of chalcones with primary amines

Gu, Lijun,He, Yonghui,Li, Ganpeng,Zeng, Dongwen,Zhang, Lizhu

, (2021/12/01)

Synthesis of aziridines by electrochemical oxidative annulation of chalcone 1,3-diphenyl-2-propen-1-one with primary amines has been developed under external oxidant - and base-free conditions. The reaction constitutes a new transformation of chalcones with primary amines to aziridines, providing a complementary, simple, and environmentally friendly approach to the currently available methods. A reaction mechanism for this transformation has been proposed based on the cyclic voltammetry.

Oxygenation of Simple Olefins through Selective Allylic C?C Bond Cleavage: A Direct Approach to Cinnamyl Aldehydes

Liu, Jianzhong,Wen, Xiaojin,Qin, Chong,Li, Xinyao,Luo, Xiao,Sun, Ao,Zhu, Bencong,Song, Song,Jiao, Ning

supporting information, p. 11940 - 11944 (2017/09/20)

A novel metal-free allylic C?C σ-bond cleavage of simple olefins to give valuable cinnamyl aldehydes is reported. 1,2-Aryl or alkyl migration through allylic C?C bond cleavage occurs in this transformation, which is assisted by an alkyl azide reagent. This method enables O-atom incorporation into simple unfunctionalized olefins to construct cinnamyl aldehydes. The reaction features simple hydrocarbon substrates, metal-free conditions, and high regio- and stereoselectivity.

Selective transformation of N-(propargylic)hydroxylamines into 4-isoxazolines and acylaziridines promoted by metal salts

Wada, Norihiro,Kaneko, Kentaro,Ukaji, Yutaka,Inomata, Katsuhiko

scheme or table, p. 440 - 442 (2011/06/23)

Cyclization of N-(propargylic)hydroxylamines catalyzed by AgBF4 afforded the corresponding 4-isoxazolines in good yields. Copper salts were found to promote the further transformation to acylaziridines. The combined use of AgBF4 and CuCl realiz
