64312-78-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64312-78-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,3,1 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64312-78:
(7*6)+(6*4)+(5*3)+(4*1)+(3*2)+(2*7)+(1*8)=113
113 % 10 = 3
So 64312-78-3 is a valid CAS Registry Number.

Phase-Transfer Catalyzed Synthesis of Amides and Esters of Carboxylic Acids
Jaszay, Zsuzsa M.,Petnehazy, Imre,Toeke, Laszlo
, p. 745 - 747 (2007/10/02)
A convenient one-pot procedure is reported for the preparation of carboxamides and carboxylic acid esters from carboxylic acids and amines or alcohols, respectively.The carboxylic acids are activated by sulfonyl chlorides under solid-liquid phase-transfer conditions using solid potassium carbonate as base and a lipophilic quaternary ammonium salt as catalyst.
