3,4-Pyridinedicarboxylic acid anhydride, also known as quinolinic anhydride, is a chemical compound with the molecular formula C7H3NO3. It is a white crystalline solid that is derived from the dehydration of 3,4-pyridinedicarboxylic acid, which contains two carboxyl groups attached to a pyridine ring. This anhydride is an important intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. It is used in the preparation of quinolone antibiotics, such as nalidixic acid and ciprofloxacin, as well as in the production of certain dyes and pigments. Due to its reactivity, it is essential to handle quinolinic anhydride with care, as it can be harmful if inhaled, ingested, or absorbed through the skin.

466-48-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 466-48-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 466-48:
(5*4)+(4*6)+(3*6)+(2*4)+(1*8)=78
78 % 10 = 8
So 466-48-8 is a valid CAS Registry Number.
