Tris(o-diphenylphosphinomethyl)phenylarsine, also known as Tris, is a chemical compound with the molecular formula C33H27AsP3. It is a trivalent organoarsenic compound characterized by a central phenyl group (C6H5) bonded to three o-diphenylphosphinomethyl groups (C6H4P(H)2). Tris<(o-diphenylphosphinomethyl)-phenyl>arsin is of interest in organometallic chemistry and has potential applications in the synthesis of various organoarsenic compounds. Tris is a colorless solid, soluble in organic solvents, and is sensitive to air and moisture. Due to its complex structure and unique properties, it has been studied for its potential use in materials science, pharmaceuticals, and as a precursor in the synthesis of other organoarsenic compounds.
The CAS Registry Mumber 97909-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,9,0 and 9 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 97909-50: (7*9)+(6*7)+(5*9)+(4*0)+(3*9)+(2*5)+(1*0)=187 187 % 10 = 7 So 97909-50-7 is a valid CAS Registry Number.
