1,2,3,9-Tetramethoxy-6,7-dihydro-5H-dibenzo[a,c][7]annulene is a complex organic compound characterized by its unique molecular structure. It belongs to the class of dibenzo[a,c]annulenes, which are a type of polycyclic aromatic hydrocarbons. This specific compound features a dihydro-5H-dibenzo[a,c][7]annulene core, which is a seven-membered ring fused to a benzene ring. The molecule is further distinguished by the presence of four methoxy groups attached to the 1, 2, 3, and 9 positions, which contribute to its polarity and solubility properties. The dihydro prefix indicates that the molecule has two hydrogen atoms added to a fully unsaturated system, which can affect its reactivity and stability. 1,2,3,9-tetramethoxy-6,7-dihydro-5H-dibenzo[a,c][7]annulene is of interest in organic chemistry and may have potential applications in materials science or as a precursor in the synthesis of more complex molecules.

The CAS Registry Mumber 4998-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,9 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.Calculate Digit Verification of CAS Registry Number 4998-58:
(6*4)+(5*9)+(4*9)+(3*8)+(2*5)+(1*8)=147
147 % 10 = 7
So 4998-58-7 is a valid CAS Registry Number.
