Sodium perfluorodecanesulfonate (PFDS) is a synthetic, fluorinated organic compound characterized by a perfluorinated alkyl chain and a sulfonate head group. It belongs to the family of perfluorinated surfactants, which are known for their unique properties such as high chemical and thermal stability, low surface tension, and resistance to degradation. PFDS is often used in various industrial applications, including as a surfactant in firefighting foams, as a component in water and stain repellents, and in the production of non-stick coatings. Due to its persistence in the environment and potential health risks, there has been growing concern about the use and disposal of PFDS, leading to increased regulation and research into safer alternatives.
The CAS Registry Mumber 2806-15-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,0 and 6 respectively; the second part has 2 digits, 1 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2806-15: (6*2)+(5*8)+(4*0)+(3*6)+(2*1)+(1*5)=77 77 % 10 = 7 So 2806-15-7 is a valid CAS Registry Number.
