The chemical compound "W(CO)4(P(C6H5)2CH(COC6H4CH3)P(C6H5)2)" is a complex organometallic compound consisting of a tungsten (W) center. It features four carbonyl (CO) ligands, which are linear molecules that bind to the metal through a triple bond. Additionally, it has two diphenylphosphino (P(C6H5)2) groups and a unique chelating diphenylphosphino ligand, which is attached to the tungsten through a carbon atom and also contains a benzyl group (C6H4CH3) and a carbonyl group (C=O). This structure gives the compound a chelating effect, where the ligand wraps around the metal center, enhancing the stability of the complex. The compound is significant in the field of homogeneous catalysis due to its potential applications in various chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 91382-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,3,8 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 91382-18:
(7*9)+(6*1)+(5*3)+(4*8)+(3*2)+(2*1)+(1*8)=132
132 % 10 = 2
So 91382-18-2 is a valid CAS Registry Number.
