5-Jod-isophthalsaeure-mono-n-pentylester-mononatriumsalz, also known as sodium mono-5-iodo-isophthalate mono-n-pentyl ester, is a chemical compound with the molecular formula C12H12INO4. It is a derivative of isophthalic acid, which is a dicarboxylic acid used in the production of various polymers and plastics. In 5-Jod-isophthalsaeure-mono-n-pentylester-mononatriumsalz, one of the carboxyl groups is esterified with a n-pentyl group, and the other is neutralized with sodium to form a salt. The presence of the iodine atom in the 5-position of the isophthalic acid structure gives 5-Jod-isophthalsaeure-mono-n-pentylester-mononatriumsalz unique properties, such as increased thermal stability and flame retardancy. It can be used in the synthesis of specialty polymers, pharmaceuticals, and other chemical products.

Check Digit Verification of cas no

The CAS Registry Mumber 4980-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4980-91:
(6*4)+(5*9)+(4*8)+(3*0)+(2*9)+(1*1)=120
120 % 10 = 0
So 4980-91-0 is a valid CAS Registry Number.
