"W(CO)4(P(OC6H5)3)CS" is a complex organometallic compound, featuring a tungsten (W) center. It consists of four carbonyl (CO) ligands, which are common π-acceptor ligands that bind to the metal through carbon. Attached to the tungsten is a phosphorus (P) atom, which is part of a phosphine ligand, specifically triphenylphosphine (P(OC6H5)3), where each of the three phenyl groups is a ring of six carbon atoms with hydrogen atoms attached. The compound also includes a thiocarbonyl ligand (CS), which is a sulfur analog of a carbonyl ligand, providing a sulfur atom for bonding. W(CO)4(P(OC6H5)3)CS is an example of a metal carbonyl complex, which are important in organometallic chemistry and catalysis, and can exhibit unique electronic properties and reactivity due to the presence of both metal and organic ligands.
The CAS Registry Mumber 65969-60-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,6 and 9 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 65969-60: (7*6)+(6*5)+(5*9)+(4*6)+(3*9)+(2*6)+(1*0)=180 180 % 10 = 0 So 65969-60-0 is a valid CAS Registry Number.
