Phosphonic chloride fluoride, ethyl-, also known as ethylphosphonic dichloride fluoride or ethylphosphonochloridifluoride, is a chemical compound with the molecular formula C2H5Cl2FPO. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. Phosphonic chloride fluoride, ethyl- is primarily used as a reagent in the synthesis of various organophosphorus compounds, particularly in the production of agrochemicals and pharmaceuticals. It is also employed as a flame retardant and a catalyst in chemical reactions. Due to its reactivity and potential health hazards, it is essential to handle ethylphosphonic chloride fluoride with proper safety measures and precautions.
The CAS Registry Mumber 865-61-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,6 and 5 respectively; the second part has 2 digits, 6 and 1 respectively. Calculate Digit Verification of CAS Registry Number 865-61: (5*8)+(4*6)+(3*5)+(2*6)+(1*1)=92 92 % 10 = 2 So 865-61-2 is a valid CAS Registry Number.
