"6,6',7,7'-tetramethoxy-Δ3,3'-biphthalide" is a complex organic compound characterized by its unique structure and properties. It is a derivative of biphthalide, which is a type of phthalide, a class of organic compounds that are cyclic esters of benzoic acid. The compound is distinguished by the presence of four methoxy groups (-OCH3) attached to the 6, 6', 7, and 7' positions of the biphthalide molecule. The Δ3,3' notation indicates a specific geometric isomerism, suggesting that the molecule has a double bond between the 3 and 3' carbon atoms, which can affect its chemical reactivity and physical properties. 6,6',7,7'-tetramethoxy-Δ3,3'-biphthalide is likely to be found in the field of organic chemistry, potentially used in the synthesis of pharmaceuticals, dyes, or other specialty chemicals due to its specific structural features.
The CAS Registry Mumber 2504-53-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,0 and 4 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2504-53: (6*2)+(5*5)+(4*0)+(3*4)+(2*5)+(1*3)=62 62 % 10 = 2 So 2504-53-2 is a valid CAS Registry Number.
