Sodium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-1-octanesulfonate, also known as Nafion-H, is a perfluorinated sulfonic acid salt with the chemical formula C8F17SO3Na. It is a highly fluorinated, water-soluble ionic compound that exhibits unique properties due to its strong electronegativity and hydrophobic nature. Nafion-H is widely used in various applications, such as proton exchange membranes in fuel cells, gas separation membranes, and catalysts in chemical reactions. Its chemical structure consists of a perfluorinated carbon chain with a sulfonate group at one end, which imparts its strong acidity and solubility in water. The compound's stability, chemical resistance, and thermal properties make it a valuable material in the field of materials science and chemical engineering.

Check Digit Verification of cas no

The CAS Registry Mumber 4021-47-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4021-47:
(6*4)+(5*0)+(4*2)+(3*1)+(2*4)+(1*7)=50
50 % 10 = 0
So 4021-47-0 is a valid CAS Registry Number.
