6-Phenylpyridazine-3-carbaldehyde is an organic compound characterized by its molecular formula C12H8N2O. It is a derivative of pyridazine, a heterocyclic aromatic compound consisting of a six-membered ring with two nitrogen atoms and four carbon atoms. The "6-phenyl" part of its name indicates that a phenyl group (a benzene ring with a hydrogen atom replaced by a carbon-carbon bond) is attached to the sixth carbon of the pyridazine ring. The "3-carbaldehyde" part signifies the presence of a formyl group (-CHO) at the third position of the pyridazine ring. 6-phenylpyridazine-3-carbaldehyde is often used as an intermediate in the synthesis of various pharmaceuticals and agrochemicals due to its unique chemical structure and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 99974-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,7 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99974-22:
(7*9)+(6*9)+(5*9)+(4*7)+(3*4)+(2*2)+(1*2)=208
208 % 10 = 8
So 99974-22-8 is a valid CAS Registry Number.

supporting information, p. 9244 - 9247 (2019/06/04)

Mono- or bidentate boron Lewis acids trigger a regioselective magnesiation or zincation of pyridazine in position C3 (ortho product) or C4 (meta product). The regioselectivity of the metalation was rationalized with the help of calculated pKa values of both pyridazine and pyridazine/Lewis acid complexes.
