1,2,3,4,5,6-Hexachloro-1,1,2,3,4,5,6,6-octafluorohexane is a complex organic compound with the chemical formula C6Cl6F8. It consists of a hexane molecule with all six hydrogen atoms replaced by fluorine atoms and three of the carbon atoms substituted with chlorine atoms. 1,2,3,4,5,6-Hexachloro-1,1,2,3,4,5,6,6-octafluorohexane is characterized by its highly chlorinated and fluorinated structure, which contributes to its unique properties. It is a colorless, odorless, and nonflammable liquid with a high boiling point and low solubility in water. Due to its chemical stability and resistance to decomposition, it has been used in various industrial applications, such as a refrigerant and a fire-extinguishing agent. However, its production and use have been restricted or banned in many countries due to its potential environmental and health risks, as it is a persistent organic pollutant and can accumulate in the environment and the food chain.
The CAS Registry Mumber 307-25-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 7 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 307-25: (5*3)+(4*0)+(3*7)+(2*2)+(1*5)=45 45 % 10 = 5 So 307-25-5 is a valid CAS Registry Number.
