2-(1-methylbenzylidene)azino-3-p-tolyl-5-carboxymethylenethiazolidione-4-one is a complex organic compound with the molecular formula C21H18N2O2S. It is characterized by a thiazolidione ring, which is a five-membered ring containing sulfur, carbon, and nitrogen atoms. The compound features a 1-methylbenzylidene group attached to the 2-position of the azino group, and a p-tolyl group (a tolyl group with a para-methyl substitution) at the 3-position. Additionally, it has a carboxymethylene group at the 5-position, which is a methylene group (CH2) bonded to a carboxyl group (COOH). This chemical structure suggests potential applications in pharmaceuticals or as a synthetic intermediate due to its diverse functional groups and aromatic components.
The CAS Registry Mumber 5213-41-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 3 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5213-41: (6*5)+(5*2)+(4*1)+(3*3)+(2*4)+(1*1)=62 62 % 10 = 2 So 5213-41-2 is a valid CAS Registry Number.
