398-70-9

2,5-difluorostyrene is an organic compound with the chemical formula C8H6F2. It is a derivative of styrene, where two hydrogen atoms are replaced by fluorine atoms at the 2nd and 5th carbon positions. This halogenated aromatic compound is characterized by its unique electronic properties due to the presence of fluorine atoms, which can influence its reactivity and stability. 2,5-difluorostyrene is of interest in the field of materials science and organic chemistry, particularly for its potential applications in the synthesis of polymers and other specialty chemicals. It can be used as a monomer in the production of fluoropolymers, which are known for their heat resistance, chemical resistance, and low refractive index. The compound's synthesis typically involves the fluorination of styrene or other related compounds, and it is often handled under controlled conditions due to its reactivity.

398-70-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 398-70-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,9 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 398-70:
(5*3)+(4*9)+(3*8)+(2*7)+(1*0)=89
89 % 10 = 9
So 398-70-9 is a valid CAS Registry Number.
