Check Digit Verification of cas no

The CAS Registry Mumber 68057-10-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,5 and 7 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 68057-10:
(7*6)+(6*8)+(5*0)+(4*5)+(3*7)+(2*1)+(1*0)=133
133 % 10 = 3
So 68057-10-3 is a valid CAS Registry Number.

Ammonium nitrate: A biodegradable and efficient catalyst for the direct amidation of esters under solvent-free conditions

Ramesh, Perla,Fadnavis, Nitin W.

, p. 138 - 140 (2015)

A simple, metal-free, and environment-friendly procedure is developed for the direct conversion of esters to amides using ammonium nitrate as a catalyst under solvent-free conditions. Aryls, heteroaryls, and aliphatic esters are easily converted to the corresponding amides in excellent isolated yields (85-99%). An enantiopure ester and amine were both shown to react without racemization. The methodology has been successfully applied to preparation of procainamide.

Transamidation of primary amides with amines catalyzed by zirconocene dichloride

Atkinson, Benjamin N.,Chhatwal, A. Rosie,Lomax, Helen V.,Walton, James W.,Williams, Jonathan M. J.

supporting information, p. 11626 - 11628 (2013/01/15)

Zirconocene dichloride (Cp2ZrCl2) has been shown to be an effective catalyst for the transamidation of primary amides with amines in cyclohexane at 80°C in 5-24 hours. For favourable substrates, the reaction can be performed at temperatures as low as 30°C.
