76415-97-9 Usage
General Description
Perfluoropolyether (PFPE) is a family of chemical compounds that are characterized by having a backbone of alternating oxygen and fluorine atoms, with attached side chains made up of carbon and fluorine atoms. These compounds are known for their excellent thermal and chemical stability, as well as their low surface tension and nonflammability. PFPEs are commonly used as lubricants and in electronic and semiconductor manufacturing due to their ability to provide friction reduction, heat resistance, and chemical inertness. They are also used as heat transfer fluids, in hydraulic systems, and in various other industrial applications. Despite their beneficial properties, concerns have been raised about the potential environmental and health impacts of PFPEs, particularly the persistence and bioaccumulation of certain chemical forms within this family.
Check Digit Verification of cas no
The CAS Registry Mumber 76415-97-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,1 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 76415-97:
(7*7)+(6*6)+(5*4)+(4*1)+(3*5)+(2*9)+(1*7)=149
149 % 10 = 9
So 76415-97-9 is a valid CAS Registry Number.
