1,2-dichloro-1,1,2,3,4,4,5,5,5-nonafluoro-3-trifluoromethyl-pentane is a complex organic compound with the molecular formula C5Cl2F9. It is a halogenated hydrocarbon, specifically a chlorofluorocarbon (CFC), characterized by the presence of two chlorine atoms and nine fluorine atoms. The compound features a pentane backbone with a trifluoromethyl group attached to the third carbon. Due to its highly fluorinated nature, this chemical exhibits unique properties such as low reactivity, high thermal stability, and low boiling points. However, it is important to note that the release of such compounds into the atmosphere can contribute to ozone depletion and have adverse environmental impacts, which is why their production and use have been regulated under international agreements like the Montreal Protocol.
The CAS Registry Mumber 1998-80-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 8 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 1998-80: (6*1)+(5*9)+(4*9)+(3*8)+(2*8)+(1*0)=127 127 % 10 = 7 So 1998-80-7 is a valid CAS Registry Number.
