The given chemical compound is a complex molecule consisting of a cyclopentadienyl anion (C5H5-), a nickel(II) ion (Ni2+), an iodide ion (I-), and a tris(triphenylantimony) ligand (Sb(C6H5)3). The compound can be represented as C5H5NiI{Sb(C6H5)3}, where the cyclopentadienyl anion acts as a ligand, coordinating to the nickel(II) ion. The iodide ion is also coordinated to the nickel(II) ion, while the tris(triphenylantimony) ligand is attached to the nickel(II) ion through the antimony atom. This complex molecule exhibits a unique structure and properties due to the presence of multiple ligands and the central metal ion.
The CAS Registry Mumber 1298-83-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1298-83: (6*1)+(5*2)+(4*9)+(3*8)+(2*8)+(1*3)=95 95 % 10 = 5 So 1298-83-5 is a valid CAS Registry Number.
