Exo-4-syn-8-dichloro-2,3:6,7-dibenzobicyclo[3.2.1]octa-2,6-diene is a complex organic compound with a unique bicyclic structure. It consists of two benzene rings connected through a cyclopropane ring, with a double bond between the second and third carbon atoms and another double bond between the sixth and seventh carbon atoms. The compound is characterized by the presence of two chlorine atoms, one attached to the fourth carbon atom and the other to the eighth carbon atom. The exo and syn prefixes indicate the relative positions of the chlorine atoms and the double bonds, with exo referring to the chlorine atom being on the outside of the molecule and syn indicating that the double bonds are on the same side of the molecule. exo-4-syn-8-dichloro-2,3:6,7-dibenzobicyclo<3.2.1>octa-2,6-diene has potential applications in the synthesis of various pharmaceuticals and agrochemicals due to its structural complexity and reactivity.
The CAS Registry Mumber 2197-98-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2197-98: (6*2)+(5*1)+(4*9)+(3*7)+(2*9)+(1*8)=100 100 % 10 = 0 So 2197-98-0 is a valid CAS Registry Number.
