147917-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 147917-04-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,9,1 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 147917-04:
(8*1)+(7*4)+(6*7)+(5*9)+(4*1)+(3*7)+(2*0)+(1*4)=152
152 % 10 = 2
So 147917-04-2 is a valid CAS Registry Number.

REACTION OF POLYFLUOROACYLPYRUVIC ESTERS WITH N-DINUCLEOPHILES
Kondrat'ev, P. N.,Skryabina, Z. E.,Saloutin, V. I.,Khalilov, L. M.
, p. 1085 - 1091 (2007/10/02)
According to the 13C NMR spectra, polyfluoroacylpyruvic esters are enolized at the carbonyl carbon atom attached to the ester group. The reaction of these compounds with ethylenediamine (o-phenylenediamine) takes place at the α-keto ester fragment of the
