7,8-diaza[5]helicene N,N'-dioxide is a unique organic compound characterized by its helicene structure, which features a helical shape. This molecule is composed of a central five-membered ring with two nitrogen atoms at positions 7 and 8, and two oxygen atoms attached to the nitrogen atoms, forming the N,N'-dioxide group. The helicene structure is known for its chirality, which means it cannot be superimposed on its mirror image, a property that is significant in the field of asymmetric synthesis and chiral recognition. The compound's helical arrangement of atoms endows it with specific optical properties, making it a subject of interest in materials science and chemistry for potential applications in areas such as chiral catalysts, sensors, and optical devices.

Check Digit Verification of cas no

The CAS Registry Mumber 7263-40-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,6 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7263-40:
(6*7)+(5*2)+(4*6)+(3*3)+(2*4)+(1*0)=93
93 % 10 = 3
So 7263-40-3 is a valid CAS Registry Number.

A simple approach for the synthesis of 7,8-diaza[5]helicene

Caronna, Tullio,Fontana, Francesca,Mele, Andrea,Sora, Isabella Natali,Panzeri, Walter,Vigano, Luca

, p. 413 - 416 (2008/09/20)

An oxidative route for the formation of 7,8-diaza[5]helicene and the corresponding N-oxides in high yields was developed. A mechanism of formation and possible interconversion of these products is put forward. Reduction of the N-oxides provided the title compound in quantitative yield. Georg Thieme Verlag Stuttgart.
