92152-55-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92152-55-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,5 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 92152-55:
(7*9)+(6*2)+(5*1)+(4*5)+(3*2)+(2*5)+(1*5)=121
121 % 10 = 1
So 92152-55-1 is a valid CAS Registry Number.

Method for synthesizing thioester through cross-coupling of visible light-catalyzed sodium sulfinate and acyl chloride

-

Paragraph 0056-0059, (2021/09/11)

The method takes sodium sulfinate and acyl chloride as raw materials and utilizes 2, 6 - dimethyl -1, 4 - dihydro -3, 5 - pyridine dicarboxylic acid diethyl ester and an organic alkali catalytic system to cross-couple sulfur radicals and acyl radicals und

Method for producing thioesters by means of oxo thio acetic acid compounds

-

Paragraph 0056; 0057; 0071-0076; 0084-0089, (2019/12/02)

The invention provides a method for preparing thioesters from oxo thio acetic acid compounds. In the presence of a palladium catalyst, a phosphine ligand and an organic solvent, an oxo thio acetic acid compound is decarboxylated and then reacts with an ar

Oxalic Acid Monothioester for Palladium-Catalyzed Decarboxylative Thiocarbonylation and Hydrothiocarbonylation

Zhao, Bin,Fu, Yao,Shang, Rui

, p. 9521 - 9526 (2019/11/28)

Oxalic acid monothioester (OAM), an easily accessible and storable reagent, was reported herein as a thioester synthetic equivalent for palladium-catalyzed decarboxylative thiocarbonylation of organohalides and hydrothiocarbonylation of unsaturated carbon-carbon bonds at room temperature with high chemo- and regioselectivity. The reaction is applicable to the synthesis of cysteine-derived thioesters, thus allowing chemical modification of cysteine-containing peptides. Decarboxylation of OAM proceeds through oxidative addition of Pd(0) to the acyl-S bond, which accounts for the very mild reaction conditions.
