133405-24-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133405-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,0 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133405-24:
(8*1)+(7*3)+(6*3)+(5*4)+(4*0)+(3*5)+(2*2)+(1*4)=90
90 % 10 = 0
So 133405-24-0 is a valid CAS Registry Number.

Alkoxyperfluoroalkylation of Enol Ethers Catalysed by Iron Complexes
Sasaoka, Shin-ichi,Uno, Mitsunari,Joh, Takashi,Imazaki, Hideyuki,Takahashi, Sigetoshi
, p. 86 - 87 (1991)
The iron-catalysed coupling reaction of three components, perfluoroalkyl iodides, enol ethers and alcohols, in the presence of a base gives directly perfluoroalkyl-substituted acetals in good to excellent yields.
