428-97-7 Usage
General Description
Diethyl 2,2-difluoropentanedioate is a unique chemical compound that belongs to the family of esters, which are chemical compounds derived from acids. The structure of this chemical features a pentanedioate backbone with two fluorine atoms replacing two hydrogen atoms, and two ethyl groups attached to the terminal carbons. It is primarily used in research settings and is often used in the synthesis of other chemicals or as a chemical reagent in various organic reactions. Like many fluorochemicals, it’s utilized for its unique chemical characteristics associated with the presence of fluorine atoms in the compound, which can influence reactivity and the physical properties of the molecule.
Check Digit Verification of cas no
The CAS Registry Mumber 428-97-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 428-97:
(5*4)+(4*2)+(3*8)+(2*9)+(1*7)=77
77 % 10 = 7
So 428-97-7 is a valid CAS Registry Number.
