184765-38-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 184765-38-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,4,7,6 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 184765-38:
(8*1)+(7*8)+(6*4)+(5*7)+(4*6)+(3*5)+(2*3)+(1*8)=176
176 % 10 = 6
So 184765-38-6 is a valid CAS Registry Number.

One-pot esterification and amide formation via acid-catalyzed dehydration and ritter reactions

Dawar, Pankaj,Raju, M. Bagavan,Ramakrishna, Ramesha Andagar

supporting information, p. 836 - 846 (2014/03/21)

Esterification of carboxylic acid is achieved using acetonitrile as a water trap. Water liberated during esterification is consumed in cyanide hydrolysis, thereby driving the esterification to completion. Substrates having carboxylic acid and nitrile groups undergo intramolecular dehydration and rehydration to amido esters in the absence of acetonitrile. Cyano acids also undergo esterification and Ritter reaction in one pot when excess alcohol is used. For the first time, we have observed an interesting Ritter reaction of primary alcohols, leading to ester amide product in one pot. [Supplementary materials are available for this article.
