Alpha-Phosphinylbenzyl alcohol, also known as (diphenylphosphino)methyl alcohol or 1-(diphenylphosphino)ethanol, is an organophosphorus compound with the chemical formula C14H13OH2P. It is a colorless to pale yellow liquid and is soluble in common organic solvents. alpha-Phosphinylbenzyl alcohol is widely used as a ligand in homogeneous catalysis, particularly in transition metal-catalyzed reactions, due to its ability to form stable complexes with metals. It is also employed in the synthesis of various phosphorus-containing compounds and as a reagent in organic chemistry. The compound is sensitive to air and moisture, and it is typically stored under an inert atmosphere to prevent degradation.

Check Digit Verification of cas no

The CAS Registry Mumber 4392-98-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,9 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4392-98:
(6*4)+(5*3)+(4*9)+(3*2)+(2*9)+(1*8)=107
107 % 10 = 7
So 4392-98-7 is a valid CAS Registry Number.
