Undecahelicene is a polycyclic aromatic hydrocarbon (PAH) consisting of eleven fused benzene rings arranged in a helical structure. It is a member of the helicene family, which are chiral molecules with a helical shape. Undecahelicene is of interest in the field of organic chemistry and materials science due to its unique structure and potential applications in the development of new materials and technologies. The molecule exhibits interesting optical properties, such as circular dichroism, which makes it a subject of study for potential use in chiral recognition and sensing applications. Additionally, its synthesis and stability are challenging, which has led to ongoing research in the development of efficient synthetic routes and understanding its electronic properties.

Check Digit Verification of cas no

The CAS Registry Mumber 57468-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,4,6 and 8 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57468-45:
(7*5)+(6*7)+(5*4)+(4*6)+(3*8)+(2*4)+(1*5)=158
158 % 10 = 8
So 57468-45-8 is a valid CAS Registry Number.
