The given chemical formula represents a complex compound consisting of vanadyl (VO^(2+)), a methyl ester of phenylphosphonic acid (CH3OC6H4PO3^(2-)), a water molecule (H2O), and an ethanol molecule (C2H5OH). VO(2+)*CH3OC6H4PO3(2-)*H2O*C2H5OH=VO(CH3OC6H4PO3)*H2O*C2H5OH can be described as a vanadyl complex with a phenylphosphonate ligand, where the vanadyl ion is coordinated to the phenylphosphonate group. The presence of a water molecule and an ethanol molecule suggests that VO(2+)*CH3OC6H4PO3(2-)*H2O*C2H5OH=VO(CH3OC6H4PO3)*H2O*C2H5OH may be a solvate or a hydrate, indicating that these solvent molecules are part of the crystal structure. The overall formula indicates a coordination complex with a metal ion (vanadyl), an organic ligand (phenylphosphonate), and solvent molecules, which are characteristic of many coordination compounds in chemistry.
The CAS Registry Mumber 92669-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,6 and 9 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 92669-40: (7*9)+(6*2)+(5*6)+(4*6)+(3*9)+(2*4)+(1*0)=164 164 % 10 = 4 So 92669-40-4 is a valid CAS Registry Number.
