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 complex with a phosphine ligand. The compound is a salt formed by the combination of these two ions, with the overall charge being neutral. The vanadium complex has a central vanadium atom coordinated to five carbonyl (CO) ligands and one bidentate phosphine ligand, which itself is a derivative of triphenylphosphine with two ethyl groups attached to the central carbon atom. This type of complex is often used in organometallic chemistry and catalysis due to its unique electronic and steric properties.

Check Digit Verification of cas no

The CAS Registry Mumber 82887-85-2 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 82887-85:
(7*8)+(6*2)+(5*8)+(4*8)+(3*7)+(2*8)+(1*5)=182
182 % 10 = 2
So 82887-85-2 is a valid CAS Registry Number.
