The given chemical compound is a complex ion, consisting of a cation and an anion. The cation is (C2H5)4N+, which is tetraethylammonium (TEA), a quaternary ammonium salt. The anion is V(CO)5(P(C6H5)2CH2CH2P(C2H5)2)-, a vanadium carbonyl complex with two diphenylphosphinoethane (dppe) ligands. (C2H5)4N(1+)*V(CO)5(P(C6H5)2CH2CH2P(C2H5)2)(1-) is a coordination complex, where the vanadium atom is coordinated to five carbonyl (CO) ligands and one bidentate dppe ligand. The overall charge of the complex ion is -1, indicating that it is an anionic species.

Check Digit Verification of cas no

The CAS Registry Mumber 82887-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,8,8 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82887-89:
(7*8)+(6*2)+(5*8)+(4*8)+(3*7)+(2*8)+(1*9)=186
186 % 10 = 6
So 82887-89-6 is a valid CAS Registry Number.
