90945-65-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90945-65-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,9,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90945-65:
(7*9)+(6*0)+(5*9)+(4*4)+(3*5)+(2*6)+(1*5)=156
156 % 10 = 6
So 90945-65-6 is a valid CAS Registry Number.

Decarboxylative Oxyacyloxylation of Propiolic Acids: Construction of Alkynyl-Containing α-Acyloxy Ketones

Chen, Xin,Xin, Yangchun,Zhao, Zhi-Wei,Hou, Yu-Jian,Wang, Xiang-Xiang,Xia, Wen-Jin,Li, Ya-Min

, p. 8216 - 8225 (2021/06/28)

Novel decarboxylative oxyacyloxylation of propiolic acids has been developed. This reaction provides an efficient access to alkynyl-containing α-acyloxy ketones from readily available starting materials and exhibits significant functional group tolerance. Furthermore, oxyacyloxylation of terminal alkynes and aliphatic propiolic acids was also developed. A possible reaction mechanism is proposed based on mechanistic studies.

An efficient method for the α-acetoxylation of ketones

Sheng, Jinmei,Li, Xiaolong,Tang, Mingfang,Gao, Botao,Huang, Guosheng

, p. 1165 - 1168 (2008/02/03)

α-Acetoxylation of ketones catalyzed by iodobenzene using 30% aqueous hydrogen peroxide and acetic anhydride as the oxidant is an effective and economical method for the preparation of a-acetoxy ketones. The reaction gave the products in good yields witho
