141031-05-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141031-05-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,0,3 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 141031-05:
(8*1)+(7*4)+(6*1)+(5*0)+(4*3)+(3*1)+(2*0)+(1*5)=62
62 % 10 = 2
So 141031-05-2 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.
