((2R,3R)-4-Oxo-2,3-diphenyl-3,4-dihydro-2H-benzo[b][1,4]thiazepin-5-yl)-acetic acid is a complex organic compound with a molecular formula of C21H17NO3S. It features a benzothiazepine core, which is a fused ring system consisting of a benzene ring and a thiazine ring. The compound has a 4-oxo group, indicating the presence of a carbonyl group at the 4-position, and a 2,3-diphenyl substitution, which means there are two phenyl groups attached to the 2 and 3 positions of the benzothiazepine ring. Additionally, it has a 3,4-dihydro descriptor, suggesting that the compound has two hydrogen atoms added across a double bond in the 3 and 4 positions, making it a dihydro derivative. The molecule is further characterized by a 5-yl group, which is a substituent attached to the 5-position of the benzothiazepine ring, and an acetic acid group, indicating the presence of a carboxyl group (-COOH). This chemical is known for its potential applications in the pharmaceutical industry, particularly as a precursor in the synthesis of certain drugs.
The CAS Registry Mumber 89813-79-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,1 and 3 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 89813-79: (7*8)+(6*9)+(5*8)+(4*1)+(3*3)+(2*7)+(1*9)=186 186 % 10 = 6 So 89813-79-6 is a valid CAS Registry Number.
