7789-28-8 Usage
General Description
Iron(II) fluoride, also known as ferrous fluoride, is a chemical compound with the formula FeF2. It is a greenish crystalline solid that is primarily used in the production of iron and steel, as well as in the manufacture of chemical compounds. Iron(II) fluoride is also employed as a catalyst in organic synthesis and as an ingredient in toothpaste and dental products. It is known to be a hazardous substance and can cause irritation to the eyes, skin, and respiratory system upon exposure. Additionally, ingestion of iron(II) fluoride can lead to gastrointestinal irritation and vomiting. Therefore, it is important to handle this chemical with caution and in accordance with safety guidelines.
Check Digit Verification of cas no
The CAS Registry Mumber 7789-28-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7789-28:
(6*7)+(5*7)+(4*8)+(3*9)+(2*2)+(1*8)=148
148 % 10 = 8
So 7789-28-8 is a valid CAS Registry Number.

Matrix Isolation Infrared and Moessbauer Studies of the Oxidative Addition Reactions of the Hydrogen Halides with Iron Atoms
Parker, Stewart F.,Peden, Charles H. F.,Barrett, Paul H.,Pearson, Ralph G.
, p. 1304 - 1308 (2007/10/02)
The reactions of the hydrogen halides with iron atoms in inert matrices lead to the previously unknown molecules H-Fe-X (X = Cl, Br, I).Infrared studies with Ar/Fe/HX (5percent) and Kr/Fe/HX (5percent) show one new band in the region 1735-1755 cm-1.This is assigned to the iron-hydride stretch of H-Fe-X.Moessbauer studies of Ar/Fe/HX (5percent) show the formation of one major product in each case.These products all have isomer shifts characteristic of Fe(II) complexes, hence they are similarly assigned to the oxidative addition product H-Fe-X.Moessbauer studies using Ar/Fe/HF show different behavior.At 6 K, two products are observed.These are assigned to an Fe(FH) complex, and to matrix isolated FeF2.Warming this sample to 77 K causes loss of the matrix, leaving amorphous FeF2 and FeF3.
