The chemical compound "X-ray structure of 3',4-dimethylthio-3,4'-diquinolinyl sulfide" is a complex organic molecule with a unique structure. It consists of two quinoline rings, each with a methylthio group at the 3' and 4 positions, respectively. These two quinoline rings are connected by a sulfide bridge, forming a diquinolinyl sulfide. The X-ray structure refers to the determination of the three-dimensional arrangement of atoms within the molecule using X-ray crystallography. This technique provides detailed information about the bond lengths, angles, and overall conformation of the molecule, which is crucial for understanding its properties and potential applications in fields such as pharmaceuticals or materials science.
The CAS Registry Mumber 74575-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,7 and 5 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 74575-24: (7*7)+(6*4)+(5*5)+(4*7)+(3*5)+(2*2)+(1*4)=149 149 % 10 = 9 So 74575-24-9 is a valid CAS Registry Number.
