940391-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 940391-44-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,3,9 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 940391-44:
(8*9)+(7*4)+(6*0)+(5*3)+(4*9)+(3*1)+(2*4)+(1*4)=166
166 % 10 = 6
So 940391-44-6 is a valid CAS Registry Number.

Palladium-Catalyzed Aerobic Oxidative Coupling of Amides with Arylboronic Acids by Cooperative Catalysis

Li, Yue,Wu, Hongxiang,Zeng, Zhuo

supporting information, p. 4357 - 4361 (2019/07/09)

The first fluoride and palladium co-catalyzed conversion of amide to ester through an aerobic oxidative coupling pathway is reported. This new approach presents a practical process that employs easily available oxygen and commercially available arylboronic acids as coupling partners, uses a wide range of N- tosylamides, and proceeds under mild reaction conditions. This protocol demonstrates broad functional group tolerance, and provides an alternative option to synthesize esters from N-tosylamides which obtained by simply N-functionalization of secondary amides.

A novel and efficient solvent-free and heterogeneous method for the synthesis of primary, secondary and bis-N-acylsulfonamides using metal hydrogen sulfate catalysts

Massah, Ahmad Reza,Asadi, Beheshteh,Hoseinpour, Mahdieh,Molseghi, Azadeh,Kalbasi, Roozbeh Javad,Javaherian Naghash, Hamid

experimental part, p. 7696 - 7705 (2009/12/04)

Some metal hydrogen sulfates were used as acid catalysts in the N-acylation of different sulfonamides using carboxylic acid chlorides and anhydrides as acylating agents under both heterogeneous and solvent-free conditions. Al(HSO4)3
