1-Oxo-3-(3-nitro-phenyl)-1,3-dihydro-oxazolo[3,4-a]pyridinium chloride is a complex organic compound with the molecular formula C11H8N3O3Cl. It features a pyridinium core, which is a heterocyclic aromatic ring containing nitrogen, and an oxazolopyridine structure. The compound is characterized by the presence of a nitro group (-NO2) attached to the phenyl ring, which is fused to the oxazolopyridine system. The 1-oxo group indicates the presence of a carbonyl (C=O) functional group, and the compound is protonated, as indicated by the chloride (Cl-) counterion. This chemical is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and reactivity.

Check Digit Verification of cas no
The CAS Registry Mumber 19919-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 19919-73:
(7*1)+(6*9)+(5*9)+(4*1)+(3*9)+(2*7)+(1*3)=154
154 % 10 = 4
So 19919-73-4 is a valid CAS Registry Number.
