3-Hydroxy-7-methoxy-1-pentyl-9-propyl-2-dibenzofurancarboxylic acid is a complex organic compound with the molecular formula C21H24O6. It features a dibenzofuran core structure, which is a type of aromatic compound consisting of two benzene rings fused to a furan ring. The molecule has a hydroxyl group (-OH) at the 3-position, a methoxy group (-OCH3) at the 7-position, a pentyl chain (C5H11) at the 1-position, and a propyl chain (C3H7) at the 9-position. The carboxylic acid group (-COOH) is present at the 2-position, which gives the compound its acidic properties. This chemical is known for its potential applications in pharmaceuticals and as a precursor in the synthesis of various bioactive compounds. Its specific properties, such as solubility and reactivity, can be influenced by the presence of these functional groups and the overall molecular structure.

436-74-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 436-74-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 436-74:
(5*4)+(4*3)+(3*6)+(2*7)+(1*4)=68
68 % 10 = 8
So 436-74-8 is a valid CAS Registry Number.
