4472-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4472-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4472-25:
(6*4)+(5*4)+(4*7)+(3*2)+(2*2)+(1*5)=87
87 % 10 = 7
So 4472-25-7 is a valid CAS Registry Number.

Palladium-Catalysed Synthesis of Alkyl Alkenylmethyl- and Alkenylphenylphosphinates
Yuanyao Xu,Zhong Li
, p. 240 - 242 (2007/10/02)
Alkyl alkenylmethyl- and alkenylphenylphosphinates were synthesized stereospecifically by the palladium-catalysed reaction of a monoalkyl methane- or benzenephosphonite with an alkenyl bromide in the presence of triethylamine with moderate to good yields.
