Perfluoro(4-methylcyclohexane)sulfonic acid anhydride is a complex organic compound with the chemical formula C7F15SO3. It is a colorless, odorless, and highly stable solid, known for its exceptional thermal and chemical stability. perfluoro(4-methylcyclohexane)sulfonic acid anhydride is a derivative of perfluorinated sulfonic acids, which are characterized by the presence of fully fluorinated carbon atoms. It is used in various industrial applications, such as in the production of high-performance polymers and as a precursor in the synthesis of other perfluorinated compounds. Due to its unique properties, it has also been studied for potential use in fuel cells and as a component in fire-fighting foams. However, it is important to note that perfluorinated compounds, including this anhydride, have raised environmental concerns due to their persistence and potential impact on human health and the ecosystem.
The CAS Registry Mumber 4925-17-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,2 and 5 respectively; the second part has 2 digits, 1 and 7 respectively. Calculate Digit Verification of CAS Registry Number 4925-17: (6*4)+(5*9)+(4*2)+(3*5)+(2*1)+(1*7)=101 101 % 10 = 1 So 4925-17-1 is a valid CAS Registry Number.
