1-Chloro-1,2-diphenylcyclopropane is a chemical compound with the molecular formula C17H15Cl. It is a cyclopropane derivative, featuring a three-carbon ring structure with two phenyl groups attached to the same carbon atom and a chlorine atom attached to the adjacent carbon. 1-chloro-1,2-diphenylcyclopropane is known for its strained ring structure, which results from the bond angles being significantly different from the ideal tetrahedral angle. The presence of the chlorine atom makes it a valuable intermediate in organic synthesis, particularly for the preparation of various pharmaceuticals and agrochemicals. Due to its reactivity and the potential for ring-opening reactions, it is often used in the synthesis of complex organic molecules. The compound is also of interest in the study of ring strain and the effects of such strain on chemical reactivity.

5082-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5082-83-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,8 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5082-83:
(6*5)+(5*0)+(4*8)+(3*2)+(2*8)+(1*3)=87
87 % 10 = 7
So 5082-83-7 is a valid CAS Registry Number.
