872-45-7 Usage
General Description
2,3-Dihydro-1-methyl-1H-phosphole 1-oxide, also known as phosphole oxide, is a heterocyclic compound containing a phosphorus atom. It is a clear, colorless liquid with a faint odor, and it is soluble in organic solvents. Phosphole oxide is commonly used as a ligand in organometallic chemistry, where it can coordinate with metal ions to form stable complexes. It is also used in various organic synthesis processes, including the production of pharmaceuticals and agrochemicals. Additionally, phosphole oxide has been studied for its potential application in optoelectronic devices and as a component in materials science. However, it is important to note that phosphole oxide may pose health risks, and proper precautions should be taken when handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 872-45-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 872-45:
(5*8)+(4*7)+(3*2)+(2*4)+(1*5)=87
87 % 10 = 7
So 872-45-7 is a valid CAS Registry Number.
