Perfluorodecylbenzene, also known as C10F21C6H5, is a synthetic chemical compound characterized by a benzene ring with a perfluorodecyl group attached to it. The perfluorodecyl group consists of a decyl chain (10 carbon atoms) where all hydrogen atoms are replaced by fluorine atoms, making the molecule highly stable and resistant to chemical reactions. <10-H-perfluor-decyl>-benzol is part of the perfluorinated compounds family, which are known for their unique properties such as water and oil repellency, thermal stability, and low surface energy. Perfluorodecylbenzene is used in various industrial applications, including as a surfactant, in the production of polymers, and in the formulation of coatings and lubricants. However, due to concerns about environmental persistence and potential health risks associated with some perfluorinated compounds, their use is subject to regulatory scrutiny and may be limited in certain contexts.
The CAS Registry Mumber 1691-50-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,9 and 1 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1691-50: (6*1)+(5*6)+(4*9)+(3*1)+(2*5)+(1*0)=85 85 % 10 = 5 So 1691-50-5 is a valid CAS Registry Number.
