Oxo(phenyl)[3-(trifluoromethyl)phenyl]phosphonium is a complex organic compound with the chemical formula C13H8F3OP. It is a phosphonium salt, which is a type of onium salt that contains a phosphorus atom bonded to four other atoms or groups. In this specific compound, the phosphorus atom is bonded to an oxo group (a double-bonded oxygen atom), a phenyl group (a benzene ring with a hydrogen atom removed), and a 3-(trifluoromethyl)phenyl group (a benzene ring with a trifluoromethyl group attached at the third carbon position). oxo(phenyl)[3-(trifluoromethyl)phenyl]phosphonium is often used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds and as a catalyst in various chemical reactions. Its unique structure, with the presence of a trifluoromethyl group, can impart specific reactivity and selectivity in chemical transformations.

Check Digit Verification of cas no

The CAS Registry Mumber 1643-92-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1643-92:
(6*1)+(5*6)+(4*4)+(3*3)+(2*9)+(1*2)=81
81 % 10 = 1
So 1643-92-1 is a valid CAS Registry Number.
