20502-88-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20502-88-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,0 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20502-88:
(7*2)+(6*0)+(5*5)+(4*0)+(3*2)+(2*8)+(1*8)=69
69 % 10 = 9
So 20502-88-9 is a valid CAS Registry Number.

POSSIBLE EVIDENCE FOR A NEW MECHANISM FOR REACTION OF TRIMETHYLPHOSPHINE WITH DIOXYGEN
Burkett, H. D.,Hill, W. E.,Worley, S. D.
, p. 169 - 172 (2007/10/02)
Evidence is presented suggesting that the mechanism for reaction of thrimethylphosphine with dioxygen proceeds through Me3PO2 as an intermediate.A mechanistic scheme is proposed to explain the products observed and the spectroscopic data obtained.
