Check Digit Verification of cas no

The CAS Registry Mumber 842155-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,2,1,5 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 842155-19:
(8*8)+(7*4)+(6*2)+(5*1)+(4*5)+(3*5)+(2*1)+(1*9)=155
155 % 10 = 5
So 842155-19-5 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.

Synthesis of α-hydroxyacetophenones

McLaughlin, Mark,Belyk, Kevin M.,Qian, Gang,Reamer, Robert A.,Chen, Cheng-Yi

experimental part, p. 5144 - 5148 (2012/07/03)

A general method for the preparation of α-hydroxyacetophenones is presented. Functionalized arylmagnesium species are transmetalated to the corresponding arylzinc intermediates, which undergo Cu(I)-catalyzed reaction with acetoxyacetyl chloride. Acidic hy
