5-(Perfluorooctyl)pentanol, also known as C14F28OH, is a synthetic organic compound characterized by a perfluorinated octyl chain attached to a pentanol group. This chemical is a member of the perfluoroalkyl ethoxylates (PFAS) family, which are known for their unique properties such as water and oil repellency, thermal stability, and resistance to degradation. Due to these characteristics, 5-(perfluorooctyl)pentanol and related PFAS compounds have been widely used in various industrial applications, including the production of non-stick cookware, stain-resistant fabrics, and firefighting foams. However, concerns have been raised about their environmental persistence and potential health risks, leading to increased scrutiny and regulations on their production and use.
The CAS Registry Mumber 2263-35-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,6 and 3 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2263-35: (6*2)+(5*2)+(4*6)+(3*3)+(2*3)+(1*5)=66 66 % 10 = 6 So 2263-35-6 is a valid CAS Registry Number.
