194038-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 194038-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,0,3 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 194038-44:
(8*1)+(7*9)+(6*4)+(5*0)+(4*3)+(3*8)+(2*4)+(1*4)=143
143 % 10 = 3
So 194038-44-3 is a valid CAS Registry Number.

Synthesis of a functionalized allylic phosphine oxide
Harmata, Michael,Carter, Kevin W.
, p. 3027 - 3033 (2007/10/03)
A functionalized allylic phosphine oxide has been prepared by regioselective bromination of 2-(methyldiphenylphosphinoyl)-1-propene followed by nucleophilic substitution with acetate. Hydrolysis and protection yielded the target compound.
