3-[(2-aminoacetyl)amino]-2,4,6-triiodobenzoic acid, also known as iopanoic acid, is a synthetic iodinated benzoic acid derivative. It is a radiopaque contrast agent used in medical imaging, specifically for cholegraphy, a procedure that visualizes the bile ducts. Iopanoic acid is structurally similar to bile acids, allowing it to be taken up by the liver and excreted into the bile, which enhances the visibility of the bile ducts on X-ray images. The chemical is characterized by its three iodine atoms attached to the benzene ring, which contribute to its radiopaque properties, and an amino group attached to the acetyl group, which plays a role in its interaction with the liver. It is important to note that iopanoic acid is not used for diagnostic purposes in the United States due to safety concerns, but it may still be used in other countries for specific medical applications.

4873-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4873-43-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,7 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4873-43:
(6*4)+(5*8)+(4*7)+(3*3)+(2*4)+(1*3)=112
112 % 10 = 2
So 4873-43-2 is a valid CAS Registry Number.
