Isodihydroglauconsaeure, also known as isophthalic acid, is an organic compound with the chemical formula C8H6O4. It is a white crystalline solid that is an isomer of phthalic acid, differing in the position of the methyl groups on the benzene ring. Isophthalic acid is widely used in the production of various polymers, particularly polyesters and polyamides, due to its ability to form strong, heat-resistant plastics. It is also used in the synthesis of dyes, pharmaceuticals, and other chemicals. The compound is derived from the oxidation of m-xylene or the hydrolysis of m-tolualdehyde and is an important intermediate in the chemical industry.
The CAS Registry Mumber 904-98-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,0 and 4 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 904-98: (5*9)+(4*0)+(3*4)+(2*9)+(1*8)=83 83 % 10 = 3 So 904-98-3 is a valid CAS Registry Number.
