54947-39-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54947-39-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,4 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 54947-39:
(7*5)+(6*4)+(5*9)+(4*4)+(3*7)+(2*3)+(1*9)=156
156 % 10 = 6
So 54947-39-6 is a valid CAS Registry Number.

Puntambekar, Hemalata M,Naik, D G,Kapadi, A H
, p. 793 - 794 (2007/10/02)
One-pot conversion of carboxylic acids into esters under the influence of phase transfer catalysis is reported.The method is shown to work satisfactorily for optically active acids having epimerisable α-hydrogen.
