84675-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84675-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,6,7 and 5 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84675-30:
(7*8)+(6*4)+(5*6)+(4*7)+(3*5)+(2*3)+(1*0)=159
159 % 10 = 9
So 84675-30-9 is a valid CAS Registry Number.

Synthesis of α-Fluorovinylphosphonates
Blackburn, G. Michael,Parratt, Martin J.
, p. 1417 - 1424 (2007/10/02)
A new general synthesis of α-fluorovinylphosphonates is provided by a Wadsworth-Emmons condensation of tetra-alkyl fluoromethylenebisphosphonates (1) with aldehydes and ketones.The reaction shows useful stereoselectivity favouring the less-hindered alkene
