Triethoxy-ethyl-phosphonium tetrafluoroborate is a complex organic compound with the chemical formula C8H20BF4O3P. It is a salt derived from triethoxy-ethyl-phosphonium cation and tetrafluoroborate anion. triethoxy-ethyl-phosphonium; tetrafluoroborate is characterized by its phosphonium cation, which contains a central phosphorus atom bonded to three ethoxy groups and one ethyl group. The tetrafluoroborate anion consists of a boron atom surrounded by four fluorine atoms. Triethoxy-ethyl-phosphonium tetrafluoroborate is often used as a phase-transfer catalyst, a reagent in organic synthesis, and a precursor for the preparation of other phosphonium salts. Its unique structure and properties make it a valuable compound in various chemical applications, particularly in the fields of catalysis and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 665-54-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,6 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 665-54:
(5*6)+(4*6)+(3*5)+(2*5)+(1*4)=83
83 % 10 = 3
So 665-54-3 is a valid CAS Registry Number.
