Tungsten, pentacarbonyl(trimethylphosphite-p)-, also known as tungsten carbonyl trimethyl phosphite, is a chemical compound with the formula W(CO)5(P(OMe)3). It is a derivative of tungsten hexacarbonyl, where one carbonyl ligand is replaced by a trimethyl phosphite ligand. Tungsten, pentacarbonyl(trimethylphosphite-p)- is of interest in organometallic chemistry and homogeneous catalysis due to its potential applications in the formation of various organometallic complexes and its role as a catalyst in certain chemical reactions. The compound is typically synthesized by reacting tungsten hexacarbonyl with trimethyl phosphite and is characterized by its stability and reactivity, which can be influenced by the presence of the phosphite ligand.

23306-42-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 23306-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,3,0 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 23306-42:
(7*2)+(6*3)+(5*3)+(4*0)+(3*6)+(2*4)+(1*2)=75
75 % 10 = 5
So 23306-42-5 is a valid CAS Registry Number.
