41882-23-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 41882-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,8,8 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 41882-23:
(7*4)+(6*1)+(5*8)+(4*8)+(3*2)+(2*2)+(1*3)=119
119 % 10 = 9
So 41882-23-9 is a valid CAS Registry Number.

H-β-zeolite catalyzed transamidation of carboxamides, phthalimide, formamides and thioamides with amines under neat conditions

Rao, Sadu Nageswara,Chandra Mohan, Darapaneni,Adimurthy, Subbarayappa

, p. 95313 - 95317 (2015/11/24)

Efficient transamidation of unactivated carboxamides, phthalimides, formamides and thioamides with amines under solvent-free conditions using H-β-zeolite as a green and recyclable heterogeneous catalyst is described. Easy work up, high purity of the products, recyclability and environmentally-friendly nature of the catalyst are the attractive features of the present methodology. This is the first report for the transamidation of thioamides under heterogeneous conditions.

Nafion-catalyzed microwave-assisted Ritter reaction: an atom-economic solvent-free synthesis of amides

Polshettiwar, Vivek,Varma, Rajender S.

, p. 2661 - 2664 (2008/09/19)

An atom-economic solvent-free synthesis of amides by the Ritter reaction of alcohols and nitriles under microwave irradiation is reported. This green protocol is catalyzed by solid-supported NafionNR50 with improved efficiency and reduced waste production.
