59534-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59534-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,5,3 and 4 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59534-69:
(7*5)+(6*9)+(5*5)+(4*3)+(3*4)+(2*6)+(1*9)=159
159 % 10 = 9
So 59534-69-9 is a valid CAS Registry Number.

Palladium-catalyzed preparation of dialkyl allylphosphonates. A new preparation of diethyl 2-oxoethylphosphonate
Malet,Moreno-Manas,Pleixats
, p. 2219 - 2228 (1992)
Palladium-catalyzed Michaelis-Arbuzov reaction of allyl acetates with trialkyl phosphites affords dialkyl allylphosphonates. Diethyl 2-oxoethylphosphonate is efficiently prepared by ozonization of diethyl allylphosphonate.
