2-(Cyclohex-1-enyl)-ethinyl-diphenyl-phosphin is a complex organic compound with the molecular formula C18H21P. It features a cyclohexene ring attached to an ethinyl (acetylene) group, which is further connected to a diphenylphosphin group. <2-(Cyclohex-1-enyl)-ethinyl>-diphenyl-phosphin is characterized by its unique structure, where the cyclohexene ring provides a stable, non-planar arrangement of carbon atoms, and the ethinyl group introduces a linear, triple-bonded carbon framework. The diphenylphosphin moiety, consisting of two phenyl rings attached to a phosphorus atom, adds to the molecule's complexity and potential reactivity. <2-(Cyclohex-1-enyl)-ethinyl>-diphenyl-phosphin may have applications in the fields of organic chemistry, materials science, and as a precursor in the synthesis of more complex phosphorus-containing molecules.
The CAS Registry Mumber 7608-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,0 and 8 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 7608-25: (6*7)+(5*6)+(4*0)+(3*8)+(2*2)+(1*5)=105 105 % 10 = 5 So 7608-25-5 is a valid CAS Registry Number.
