Dihexyl phosphite, also known as bis(2-hexyloxyethyl) phosphite, is a colorless liquid with the chemical formula C12H27O3P. It is an organophosphorus compound that is widely used as a stabilizer for various materials, including PVC, polyolefins, and other polymers. Dihexyl phosphite functions by chelating metal ions, which helps to prevent the degradation of these materials caused by oxidation and other chemical reactions. It is also used as a flame retardant, plasticizer, and intermediate in the synthesis of other phosphorus-containing compounds. Due to its effectiveness and versatility, dihexyl phosphite plays a significant role in the chemical industry and the production of various consumer and industrial products.

Check Digit Verification of cas no

The CAS Registry Mumber 1559-23-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1559-23:
(6*1)+(5*5)+(4*5)+(3*9)+(2*2)+(1*3)=85
85 % 10 = 5
So 1559-23-5 is a valid CAS Registry Number.
