Phenyl-trifluoromethyl-iod-phosphin, also known as phenyl(trifluoromethyl)iodophosphane, is a chemical compound with the molecular formula C7H5F3IP. It is a phosphorus-containing compound that features a phenyl group (C6H5), a trifluoromethyl group (CF3), and an iodine atom bonded to a phosphorus atom. This organophosphorus compound is often used as a reagent in organic synthesis, particularly in the formation of carbon-phosphorus bonds. Due to its reactivity and the presence of a highly electronegative iodine atom, it can act as a source of phosphorus in various chemical reactions, making it a valuable intermediate in the synthesis of complex molecules and materials.
The CAS Registry Mumber 1544-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 4 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1544-91: (6*1)+(5*5)+(4*4)+(3*4)+(2*9)+(1*1)=78 78 % 10 = 8 So 1544-91-8 is a valid CAS Registry Number.
