199664-70-5 Usage
Uses
5-(2-Fluorophenyl)-5-oxovaleric Acid is used as a reagent in the preparation of indole derivatives which act as cell protective agents. It is also used as a reagent in the catalytic N-nitroso aldol reaction of γ,δ-unsaturated δ-lactones.
Check Digit Verification of cas no
The CAS Registry Mumber 199664-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,6,6 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 199664-70:
(8*1)+(7*9)+(6*9)+(5*6)+(4*6)+(3*4)+(2*7)+(1*0)=205
205 % 10 = 5
So 199664-70-5 is a valid CAS Registry Number.

, p. 3848 - 3851 (2009)
The hypervalent iodine-catalyzed oxylactonization of ketocarboxylic acids to ketolactones was achieved in the presence of iodobenzene (10 mol %), p-toluenesulfonic acid monohydrate (20 mol %) and meta-chloroperbenzoic acid as a stoichiometric co-oxidant.
