2-(4-methoxy-styryl)-3-o-tolyl-3H-quinazolin-4-one is a complex organic compound with a molecular formula of C22H19NO3. It is characterized by a quinazolinone core, which is a fused ring system consisting of a benzene ring and a pyrimidine ring. The compound features a 4-methoxy-styryl group, which is a phenyl ring with a methoxy group at the para position and a vinyl group at the ortho position, attached to the 2-position of the quinazolinone. Additionally, a 3-o-tolyl group, which is a methyl-substituted phenyl ring, is attached to the 3-position of the quinazolinone. 2-(4-methoxy-styryl)-3-o-tolyl-3H-quinazolin-4-one is of interest in the field of medicinal chemistry, particularly for its potential as a precursor in the synthesis of biologically active molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1913-83-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,1 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1913-83:
(6*1)+(5*9)+(4*1)+(3*3)+(2*8)+(1*3)=83
83 % 10 = 3
So 1913-83-3 is a valid CAS Registry Number.

Deodhar, K. D.,Samant, S. D.,Pednekar, S. R.,Kanekar, D. S.,Inamdar, A. A.,Patkar, P. Y.

, p. 67 - 68 (2007/10/02)

Condensation of different schiff bases (II) with 2-methyl-4H-3,1-benzoxazin-4-one (I) yields 3-substituted 2-styryl-4(3H)-quinazolinones (III) in good yields.A plausible mechanism for the reaction has been suggested.
