Isobutyl phosphine, also known as 2-methylpropylphosphine, is an organophosphorus compound with the chemical formula C4H11PH2. It is a colorless, flammable liquid with a pungent odor and is used as a reagent in the synthesis of various organophosphorus compounds, such as phosphines and phosphine oxides. Isobutyl phosphine is also employed as a ligand in coordination chemistry and as a precursor in the production of flame retardants and pesticides. Due to its high reactivity and potential toxicity, it requires careful handling and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 4023-52-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4023-52:
(6*4)+(5*0)+(4*2)+(3*3)+(2*5)+(1*2)=53
53 % 10 = 3
So 4023-52-3 is a valid CAS Registry Number.
