2,2,4,5-Tetraphenyl-2-(cyclopentylmethoxy)-2,2-dihydro-1,3,2-dioxaphosphol-4-ene is a complex organic compound characterized by its unique molecular structure. It features a phosphorus atom at the core, surrounded by four phenyl groups, which are benzene rings with a hydrogen atom replaced by a carbon-carbon bond. The compound also includes a cyclopentylmethoxy group, which is a cyclopentyl group (a five-membered ring) attached to a methoxy group (an oxygen atom bonded to a methyl group). This structure is part of the 1,3,2-dioxaphospholane family, which are heterocyclic compounds with a phosphorus atom and two oxygen atoms in a five-membered ring. The specific arrangement of these groups gives the compound its distinct chemical properties, making it a potentially interesting molecule for various applications in organic chemistry and materials science.
The CAS Registry Mumber 91237-91-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,2,3 and 7 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 91237-91: (7*9)+(6*1)+(5*2)+(4*3)+(3*7)+(2*9)+(1*1)=131 131 % 10 = 1 So 91237-91-1 is a valid CAS Registry Number.
