Dimethylphosphinous iodide, with the chemical formula (CH3)2P(I)H, is an organophosphorus compound that features a phosphorus atom bonded to two methyl groups and a hydrogen atom, with an iodine atom attached to the phosphorus. It is a colorless, volatile, and moisture-sensitive liquid that is used as a reagent in organic synthesis, particularly in the formation of phosphorus-containing compounds. Due to its reactivity, it is often handled under anhydrous conditions to prevent hydrolysis. Dimethylphosphinous iodide is also known for its potential applications in the synthesis of pharmaceuticals and agrochemicals, as well as in materials science for the development of new materials with unique properties.
The CAS Registry Mumber 4731-62-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,3 and 1 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4731-62: (6*4)+(5*7)+(4*3)+(3*1)+(2*6)+(1*2)=88 88 % 10 = 8 So 4731-62-8 is a valid CAS Registry Number.
