79963-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79963-73-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,9,6 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79963-73:
(7*7)+(6*9)+(5*9)+(4*6)+(3*3)+(2*7)+(1*3)=198
198 % 10 = 8
So 79963-73-8 is a valid CAS Registry Number.

Methode generale d'obtention des α-ceto esters β-fluores
Ourari, Ali,Condom, Roger,Guedj, Roger
, p. 2707 - 2710 (2007/10/02)
A general method of synthesis of 3-alkyl (or aryl) 3-fluoro 2-oxo esters is described.The opening of glycidic esters with HF-pyridine (70percent w/w) followed by oxidation with Jones reagent, give the corresponding derivatives of fluoropyruvic esters in good yields.
