[Rh(η-C5H5)I2(PPh3)] is a rhodium-based organometallic complex, also known as rhodium(I) diiodide triphenylphosphine cyclopentadienyl. [Rh(η-C5H5)I2(PPh3)] consists of a rhodium atom at its center, coordinated to a cyclopentadienyl ligand (η-C5H5), two iodine atoms (I2), and a triphenylphosphine ligand (PPh3). The cyclopentadienyl ligand forms a strong π-bond with the rhodium atom, while the iodine and triphenylphosphine ligands provide additional stability through σ-bonds. This complex is of interest in the field of homogeneous catalysis, particularly in the hydrogenation of alkenes and other organic reactions, due to its unique electronic properties and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 12131-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,3 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12131-90:
(7*1)+(6*2)+(5*1)+(4*3)+(3*1)+(2*9)+(1*0)=57
57 % 10 = 7
So 12131-90-7 is a valid CAS Registry Number.
