12-Benzyl-7,12-dihydro-6H-benzo[2,3]thiepino[4,5-b]indole-9-carboxylic acid ethyl ester is a complex organic compound with a molecular formula of C23H21NO2S. It is a derivative of benzo[2,3]thiepino[4,5-b]indole, a tricyclic ring system consisting of a benzene, a thiophene, and an indole ring. The compound features a 12-benzyl group, which is a phenylmethyl group attached to the 12th carbon atom of the indole ring. Additionally, it has a 7,12-dihydro structure, indicating the presence of two hydrogen atoms in the 7th and 12th positions, which reduces the double bond character in these positions. The molecule also contains a 9-carboxylic acid group, which is esterified with an ethyl group, forming an ethyl ester. 12-benzyl-7,12-dihydro-6H-benzo[2,3]thiepino[4,5-b]indole-9-carboxylic acid ethyl ester is likely to be found in the field of medicinal chemistry, potentially as a precursor or intermediate in the synthesis of pharmaceuticals or other bioactive molecules.
The CAS Registry Mumber 1781-32-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,8 and 1 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1781-32: (6*1)+(5*7)+(4*8)+(3*1)+(2*3)+(1*2)=84 84 % 10 = 4 So 1781-32-4 is a valid CAS Registry Number.
