2785-32-2 Usage
General Description
3-[bis(2-ethylhexyl)phosphorylmethyl]heptane is a chemical compound commonly known as trioctylphosphine oxide (TOPO). It is a phosphorus-based organic compound that is used as a solvent extraction reagent and a surfactant in various industrial processes. TOPO is known for its ability to selectively extract and separate metal ions, particularly rare earth elements, from aqueous solutions. It is also used in the synthesis of semiconductor nanocrystals and in the purification of radioactive waste. TOPO has low toxicity and is compatible with a wide range of organic solvents, making it a versatile and valuable chemical in various scientific and industrial applications.
Check Digit Verification of cas no
The CAS Registry Mumber 2785-32-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2785-32:
(6*2)+(5*7)+(4*8)+(3*5)+(2*3)+(1*2)=102
102 % 10 = 2
So 2785-32-2 is a valid CAS Registry Number.
