2,2-Dichlor-perfluor-cyclohexanon, also known as 2,2-dichlorodecafluorocyclohexane, is a perfluorinated compound characterized by its cyclic structure and two chlorine atoms attached to the carbon atoms. It is a colorless, odorless, and non-toxic liquid with a high chemical stability, making it resistant to degradation. 2,2-Dichlor-perfluor-cyclohexanon is primarily used as a solvent in various industrial applications, such as the production of fluoropolymers and as a cleaning agent in electronic and semiconductor industries. Due to its unique properties, it has also been employed in fire-fighting foams. However, concerns have been raised regarding its environmental persistence and potential health impacts, leading to regulations and restrictions on its use in some regions.
The CAS Registry Mumber 5561-36-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,6 and 1 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5561-36: (6*5)+(5*5)+(4*6)+(3*1)+(2*3)+(1*6)=94 94 % 10 = 4 So 5561-36-4 is a valid CAS Registry Number.
