1,3-Benzenedicarboxamide, 5-(acetylamino)-N,N,N',N'-tetrakis(2-hydroxyethyl)-2,4,6-triiodo- is a complex organic compound with the molecular formula C20H26I3N3O8. It is a derivative of benzene dicarboxamide, featuring a benzene ring with two carboxamide groups attached at the 1 and 3 positions. The compound is further characterized by the presence of three iodine atoms at the 2, 4, and 6 positions, and an acetylamino group at the 5 position. Additionally, it has four 2-hydroxyethyl groups attached to the nitrogen atoms, which contribute to its hydrophilic properties. This chemical is known for its use as a contrast agent in medical imaging, particularly in X-ray diagnostics, where it enhances the visibility of certain tissues or organs due to its high atomic number and ability to absorb X-rays.
The CAS Registry Mumber 31127-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,2 and 7 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 31127-79: (7*3)+(6*1)+(5*1)+(4*2)+(3*7)+(2*7)+(1*9)=84 84 % 10 = 4 So 31127-79-4 is a valid CAS Registry Number.
