129271-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129271-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,7 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 129271-94:
(8*1)+(7*2)+(6*9)+(5*2)+(4*7)+(3*1)+(2*9)+(1*4)=139
139 % 10 = 9
So 129271-94-9 is a valid CAS Registry Number.

A Novel Synthesis of α-Fluoroalkylvinyl- or α-Fluoroepoxyalkyl-phosphonate
Shen, Yanchang,Liao, Qimu,Qiu, Weiming
, p. 695 - 697 (2007/10/02)
α-Fluoroalkylvinyl- or α-fluoroepoxyalkyl-phosphonates can be synthesized by the reaction of diethyl lithium phosphite with fluorinated β-oxoalkylphosphonium salts, depending upon the α-substituents R1 and R2 in the alkylidene moiety of the phosphorane us
