Trichlor-<α-chlor-styryl>-phosphonium, also known as 1-(2-chlorophenyl)-2-(trichlorophosphoranylidene)ethene, is a chemical compound with the molecular formula C8H5Cl4P. It is a derivative of phosphonium salts, characterized by the presence of a phosphonium cation (P+) bonded to three chlorine atoms and an α-chlor-styryl group. Trichlor-<α-chlor-styryl>-phosphonium is an important intermediate in the synthesis of various organophosphorus compounds, such as pesticides and flame retardants, due to its reactivity and ability to form stable phosphorus-carbon bonds. The α-chlor-styryl group, which consists of a chlorinated phenyl ring attached to a vinyl group, contributes to the compound's unique chemical properties and potential applications in the development of new materials and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 1475-85-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,7 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1475-85:
(6*1)+(5*4)+(4*7)+(3*5)+(2*8)+(1*5)=90
90 % 10 = 0
So 1475-85-0 is a valid CAS Registry Number.
