3,6-Di-N-methyl-anilino-1,2,5-trithia-cycloheptadiene-2,5-dicarboxylate-(4,7)-diethylester is a complex organic compound with the molecular formula C19H22N2O4S3. It is characterized by a cycloheptadiene core, which is a seven-membered ring with alternating single and double bonds. The molecule features two N-methyl-aniline groups attached at the 3 and 6 positions, which contribute to its aromatic nature. The 1,2,5-trithia group indicates the presence of three sulfur atoms in the ring, which enhances the compound's reactivity and stability. The dicarboxylate functionality at the 2 and 5 positions, along with the diethyl ester groups at the 4 and 7 positions, provide the molecule with potential applications in various chemical reactions and as a precursor in the synthesis of other compounds. 3,6-Di--1,2,5-trithia-cycloheptadien-dicarbonsaeure-(4,7)-diethylester is an example of a heterocycle, which is a ring structure containing atoms of different elements, and it may have applications in the fields of pharmaceuticals, materials science, or as a chemical intermediate.

Check Digit Verification of cas no

The CAS Registry Mumber 2003-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,0 and 3 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2003-77:
(6*2)+(5*0)+(4*0)+(3*3)+(2*7)+(1*7)=42
42 % 10 = 2
So 2003-77-2 is a valid CAS Registry Number.
