Phosphine, dioctyl-, also known as dioctylphosphine or (C8H17)3P, is an organophosphorus compound characterized by its phosphorus atom bonded to three octyl groups. It is a colorless, oily liquid with a pungent odor and is insoluble in water but soluble in organic solvents. Dioctylphosphine is primarily used as a ligand in organometallic chemistry, particularly in the synthesis of transition metal complexes, and as a reagent in various chemical reactions. It is also employed as a flame retardant, a stabilizer for plastics, and a catalyst in the production of certain polymers. Due to its potential toxicity and flammability, it is essential to handle dioctylphosphine with caution and in accordance with safety regulations.

Check Digit Verification of cas no

The CAS Registry Mumber 3541-77-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3541-77:
(6*3)+(5*5)+(4*4)+(3*1)+(2*7)+(1*7)=83
83 % 10 = 3
So 3541-77-3 is a valid CAS Registry Number.
