Cis-1,4-dichloro-1,2-diphenyl-but-1-en, also known as cis-stilbene, is an organic compound with the chemical formula C14H12Cl2. It is a geometric isomer of trans-stilbene, characterized by the presence of two chlorine atoms attached to the same carbon atom in the butene chain, and two phenyl rings connected to the adjacent carbon atoms. This molecule is of interest in organic chemistry due to its unique structure and potential applications in the synthesis of various compounds. It is also used as a precursor in the production of certain pharmaceuticals and as a ligand in coordination chemistry. The cis-configuration refers to the arrangement of the chlorine atoms on the same side of the double bond, which affects the molecule's physical properties and reactivity compared to its trans-isomer.
The CAS Registry Mumber 5680-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 0 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5680-55: (6*5)+(5*6)+(4*8)+(3*0)+(2*5)+(1*5)=107 107 % 10 = 7 So 5680-55-7 is a valid CAS Registry Number.
