(E)-6-methylhepta-1,3-diene is an organic compound with the molecular formula C8H14. It is a conjugated diene, which means it has two carbon-carbon double bonds separated by a single bond, and it exhibits geometric isomerism due to the presence of a double bond. The "E" in its name indicates that the two substituents on the double bond are on opposite sides of the molecule when viewed along the bond axis. (E)-6-methylhepta-1,3-diene is a colorless liquid with a strong, pungent odor and is used as a building block in the synthesis of various organic compounds, particularly in the production of fragrances and pharmaceuticals. It is also known for its reactivity in Diels-Alder reactions, a type of chemical reaction that involves the cycloaddition of a conjugated diene with an alkene or alkyne.
The CAS Registry Mumber 2783-11-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 3 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2783-11: (6*2)+(5*7)+(4*8)+(3*3)+(2*1)+(1*1)=91 91 % 10 = 1 So 2783-11-1 is a valid CAS Registry Number.
