The chemical compound "W(CO)4{(C6H5)2Sb}2CH2" is a complex organometallic molecule that features a tungsten (W) center. It is characterized by four carbonyl (CO) ligands that bind to the tungsten atom, providing stability through back-donation of electron density. The compound also contains two diphenylantimony (Sb) groups, each with two phenyl rings (C6H5), which are attached to the tungsten center. These bulky diphenylantimony ligands can influence the geometry and reactivity of the complex. Additionally, the molecule has a methylene (CH2) bridge connecting the two diphenylantimony ligands, which may affect the electronic properties and steric environment around the tungsten. W(CO)4{(C₆H₅)2Sb}2CH₂ is an example of a heavier main group element complex and could be of interest in organometallic chemistry and materials science due to its unique structure and potential applications in catalysis or as a precursor to other complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 42743-65-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,4 and 3 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42743-65:
(7*4)+(6*2)+(5*7)+(4*4)+(3*3)+(2*6)+(1*5)=117
117 % 10 = 7
So 42743-65-7 is a valid CAS Registry Number.
