WCl2(PMe3)4, also known as tungsten hexachloride tetrakis(trimethylphosphine), is a transition metal complex with the chemical formula WCl2(PMe3)4. It consists of a tungsten (W) center, two chloride (Cl) ligands, and four trimethylphosphine (PMe3) ligands. WCl₂(PMe₃)4 is a significant organometallic compound, often used as a catalyst in various chemical reactions, particularly in olefin metathesis and cross-metathesis processes. The structure of WCl2(PMe3)4 features a distorted octahedral geometry around the tungsten atom, with the two chloride ligands and four phosphine ligands occupying the coordination sites. The compound is sensitive to air and moisture, and it is typically handled under an inert atmosphere. Its applications in catalysis are due to its ability to facilitate the redistribution of carbon-carbon double bonds in organic molecules, making it a valuable tool in synthetic chemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 85798-76-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,7,9 and 8 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 85798-76:
(7*8)+(6*5)+(5*7)+(4*9)+(3*8)+(2*7)+(1*6)=201
201 % 10 = 1
So 85798-76-1 is a valid CAS Registry Number.
