(5-Methoxy-1,3-dimethyl-2-oxo-2,3-dihydro-1H-indol-3-yl)acetonitrile is a complex organic compound with the molecular formula C13H14N2O2. It is a derivative of indole, a heterocyclic aromatic organic compound that contains a benzene ring fused to a pyrrole ring. The compound features a 5-methoxy group, which is a methoxy group attached to the indole ring at the 5th position, and two methyl groups at the 1st and 3rd positions. The 2-oxo-2,3-dihydro part of the name indicates the presence of a carbonyl group (C=O) at the 2nd position and a hydrogenated (dihydro) structure. The molecule also contains an acetonitrile group, which is a cyano group (-CN) attached to an ethyl group (-CH3CH2-). (5-methoxy-1,3-dimethyl-2-oxo-2,3-dihydro-1H-indol-3-yl)acetonitrile is likely to be used in the synthesis of various pharmaceuticals and agrochemicals due to its unique structure and functional groups.
The CAS Registry Mumber 2291-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,9 and 1 respectively; the second part has 2 digits, 5 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2291-51: (6*2)+(5*2)+(4*9)+(3*1)+(2*5)+(1*1)=72 72 % 10 = 2 So 2291-51-2 is a valid CAS Registry Number.
