Pyridine, 3,4-didehydro-, also known as 3,4-dehydro-pyridine or dihydropyridine, is a heterocyclic organic compound with the molecular formula C5H5N. It is an unsaturated derivative of pyridine, where two adjacent carbon atoms in the pyridine ring have been double-bonded, resulting in a conjugated diene system. Pyridine, 3,4-didehydro- is a colorless liquid with a strong, pungent odor and is soluble in organic solvents. Dihydropyridines are important intermediates in the synthesis of various pharmaceuticals, agrochemicals, and other organic compounds. They can be synthesized through various methods, including the reduction of pyridine derivatives and the cyclization of appropriate precursors. Due to their unique chemical properties, dihydropyridines have found applications in the development of calcium channel blockers, which are widely used in the treatment of cardiovascular diseases.

Check Digit Verification of cas no

The CAS Registry Mumber 7129-66-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,2 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7129-66:
(6*7)+(5*1)+(4*2)+(3*9)+(2*6)+(1*6)=100
100 % 10 = 0
So 7129-66-0 is a valid CAS Registry Number.
