25664-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 25664-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,6 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25664-41:
(7*2)+(6*5)+(5*6)+(4*6)+(3*4)+(2*4)+(1*1)=119
119 % 10 = 9
So 25664-41-9 is a valid CAS Registry Number.

Nucleophilic displacements of 2-perfluoroalkyl-1-iodoethanes: Improved synthesis of fluorine-containing malonic esters

Trabelsi,Szoenyi,Geribaldi

, p. 177 - 181 (2007/10/03)

The replacement of iodide in 2-perfluoroalkyl-1-iodoethanes by anions derived from dialkyl malonate affords α-(2-perfluoroalkyl)ethyl malonic esters in high yields with negligible elimination and dialkylation, using bases such as K2CO3/su
