The chemical compound "2,5-bis-(3-{5-[3-(5-phenyl-[1,3,4]oxadiazol-2-yl)-phenyl]-[1,3,4]oxadiazol-2-yl}-phenyl)-[1,3,4]oxadiazole" is a complex organic molecule with a unique structure. It features a central [1,3,4]oxadiazole ring, which is a five-membered heterocyclic ring containing two oxygen atoms and one nitrogen atom. Attached to this central ring are two phenyl groups, each of which is further substituted with another [1,3,4]oxadiazol-2-yl group. These oxadiazole groups are connected to phenyl rings, which in turn are linked to a 5-phenyl-[1,3,4]oxadiazol-2-yl moiety. This intricate arrangement of rings and substituents gives the compound its specific properties and potential applications in various fields, such as materials science and pharmaceuticals.
The CAS Registry Mumber 3838-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,3 and 8 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3838-55: (6*3)+(5*8)+(4*3)+(3*8)+(2*5)+(1*5)=109 109 % 10 = 9 So 3838-55-9 is a valid CAS Registry Number.
