Tris(carbonyl)(pentamethylcyclopentadienyl)ethyltungsten is a complex organometallic compound with the chemical formula C10H15O3W. It consists of a tungsten (W) atom at the center, bonded to three carbonyl (CO) groups and a pentamethylcyclopentadienyl (C5Me5) ligand. Additionally, an ethyl (C2H5) group is attached to the tungsten atom. tris(carbonyl)(pentamethylcyclopentadienyl)ethyltungsten is known for its unique structure and potential applications in various chemical reactions, such as catalysis and organometallic synthesis. Its stability and reactivity are influenced by the strong π-bonding interaction between the tungsten and the cyclopentadienyl ligand, as well as the electron-donating nature of the methyl groups.

Check Digit Verification of cas no

The CAS Registry Mumber 83152-34-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 83152-34:
(7*8)+(6*3)+(5*1)+(4*5)+(3*2)+(2*3)+(1*4)=115
115 % 10 = 5
So 83152-34-5 is a valid CAS Registry Number.
