It consists of two hexafluorobicyclo[2.2.1]hepten-2-yl groups, which are connected through a central carbon-carbon bond. Each hexafluorobicyclo[2.2.1]hepten-2-yl group features a bicyclic structure with seven fluorine atoms attached to the carbon framework. 5,5'-Bis-<1,2,3,4,7,7-hexafluor-bicyclo<2.2.1>hepten-2-yl> is known for its stability and unique electronic properties, which can be attributed to the presence of fluorine atoms. It is often used in the synthesis of various fluorinated compounds and materials, such as polymers and pharmaceuticals, due to its ability to impart specific chemical and physical characteristics to these products.
The CAS Registry Mumber 1660-07-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,6 and 0 respectively; the second part has 2 digits, 0 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1660-07: (6*1)+(5*6)+(4*6)+(3*0)+(2*0)+(1*7)=67 67 % 10 = 7 So 1660-07-7 is a valid CAS Registry Number.
