Check Digit Verification of cas no

The CAS Registry Mumber 52097-67-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,9 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 52097-67:
(7*5)+(6*2)+(5*0)+(4*9)+(3*7)+(2*6)+(1*7)=123
123 % 10 = 3
So 52097-67-3 is a valid CAS Registry Number.

Metallic magnesium: an efficient catalyst toward N-aryl and N-alkyl substituted amides directly from aliphatic carboxylic acids

Yildirim, Ayhan

, p. 947 - 951 (2015)

Abstract An efficient and inexpensive procedure for direct conversion of aliphatic carboxylic acids into amides has been developed using anilines or aliphatic amines and Mg(0) as catalyst in toluene. The amides were obtained by single crystallization in moderate to excellent yields with high purity. Graphical Abstract: [Figure not available: see fulltext.]

Preparation of esters and amides from carboxylic acids and N-formylation of amines promoted by 1,3,5-triazo-2,4,6-triphosphorine-2,2,4,4,6,6-hexachloride (TAPC)

Bahrami, Kiumars,Khodaei, Mohammad M.,Targhan, Homa,Sheikh Arabi, Mehdi

supporting information, p. 5064 - 5068 (2013/09/02)

A new method is described for the preparation of esters and amides promoted by TAPC from carboxylic acids using a solvent-free grinding technique. The solvent-free N-formylation of amines is also reported.
