5773-09-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5773-09-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,7 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5773-09:
(6*5)+(5*7)+(4*7)+(3*3)+(2*0)+(1*9)=111
111 % 10 = 1
So 5773-09-1 is a valid CAS Registry Number.

Reaction of Oxygen Nucleophiles With β-Alkoxyvinylphosphonium Salts. Isolation of Phosphine Oxides.
Ruder, Suzanne M.,Norwood, Bradley K.
, p. 861 - 864 (2007/10/02)
A variety of β-alkoxyvinylphosphonium bromides were prepared and reacted with sodium ethoxide and dimsyl anion to generate good yields of phosphine oxides 3 rather than the previously reported ylide 4.
