The chemical compound "W(C6H5N)Cl4" is a coordination complex consisting of a tungsten (W) metal center, a phenylpyridine ligand (C6H5N), and four chloride ions (Cl-). In this complex, the tungsten atom is in the +6 oxidation state, and it forms a bond with the phenylpyridine ligand, which acts as a bidentate ligand, coordinating through both the nitrogen and one of the carbon atoms in the phenyl ring. The four chloride ions are also coordinated to the tungsten center, each carrying a -1 charge. The overall charge of the complex is neutral, as the positive charge of the tungsten center is balanced by the negative charges of the ligands. W(6+)*C6H5N(2-)*4Cl(1-)=[W(NC6H5)Cl4] is an example of a transition metal complex with organic ligands, which can have various applications in chemistry, such as catalysis and material science.
The CAS Registry Mumber 83634-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,6,3 and 4 respectively; the second part has 2 digits, 4 and 9 respectively. Calculate Digit Verification of CAS Registry Number 83634-49: (7*8)+(6*3)+(5*6)+(4*3)+(3*4)+(2*4)+(1*9)=145 145 % 10 = 5 So 83634-49-5 is a valid CAS Registry Number.
