"Cl{CF2CF(CF3)}2Cl" is a perfluorinated organochlorine compound, also known as hexachloro-1,3-butadiene or C4F6Cl6. It is a colorless liquid with a high boiling point and low solubility in water. Cl{CF2CF(CF3)}2Cl is characterized by its symmetrical structure, with two chlorine atoms attached to a central carbon atom, which is bonded to two fluorinated ethylene groups. The molecule is highly stable due to the strong carbon-fluorine bonds and the electronegativity of fluorine, which contributes to its resistance to degradation. It is used in various industrial applications, such as in the production of fluoropolymers and as a refrigerant. However, due to its persistence and potential environmental impact, its use is often subject to regulatory controls.
The CAS Registry Mumber 2110-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,1 and 0 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2110-99: (6*2)+(5*1)+(4*1)+(3*0)+(2*9)+(1*9)=48 48 % 10 = 8 So 2110-99-8 is a valid CAS Registry Number.
