131184-65-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 131184-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,8 and 4 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131184-65:
(8*1)+(7*3)+(6*1)+(5*1)+(4*8)+(3*4)+(2*6)+(1*5)=101
101 % 10 = 1
So 131184-65-1 is a valid CAS Registry Number.

Carbamoylimidazolium salts as diversification reagents: An application to the synthesis of tertiary amides from carboxylic acids

Grzyb, Justyna A.,Batey, Robert A.

, p. 7485 - 7488 (2007/10/03)

An efficient method for the preparation of tertiary amides from carbamoylimidazolium salts and carboxylic acids is described. The transformation occurs at room temperature and under relatively mild conditions. The carbamoylimidazolium salts are obtained from the reaction of secondary amines with N,N′-carbonyldiimidazole, followed by methylation with methyl iodide. The utility of this reaction was demonstrated in the formation of Weinreb amides and in a short synthesis of fused bicyclic amides. The introduction of this reaction now permits carbamoylimidazolium salts to be utilized in the formation of tertiary amides, ureas, carbamates and thiocarbamates under a single set of conditions.
