103305-01-7 Usage
General Description
Pentafluoroethylphosphonic acid, also known as PFPA, is a strong acid and a fluorinated phosphonic acid compound with the molecular formula C2HF5O3P. It is commonly used as a reagent in organic and inorganic synthesis, as well as in the production of pharmaceuticals, agrochemicals, and materials science. PFPA is highly reactive and can form stable complexes with a wide range of metals. It is also used as a building block for the synthesis of specialty chemicals and in the production of fluorinated polymers. Due to its unique properties and versatility, pentafluoroethylphosphonic acid is a valuable chemical in various industries and research applications. However, it should be handled with caution due to its corrosive and toxic nature.
Check Digit Verification of cas no
The CAS Registry Mumber 103305-01-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,3,0 and 5 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 103305-01:
(8*1)+(7*0)+(6*3)+(5*3)+(4*0)+(3*5)+(2*0)+(1*1)=57
57 % 10 = 7
So 103305-01-7 is a valid CAS Registry Number.
