It features a unique structure that includes a 5-thia-9-aza-cyclohepta[f]inden-7-yl group, which is a heterocyclic ring system with sulfur and nitrogen atoms. 2-((R)-8-Oxo-2,3,6,7,8,9-hexahydro-1H-5-thia-9-aza-cyclohepta[f]inden-7-yl)-isoindole-1,3-dione is characterized by its hexahydro nature, indicating the presence of six hydrogen atoms in a cyclic structure, and the presence of an oxo group, which is a carbonyl group (C=O). The isoindole-1,3-dione moiety suggests the presence of a fused ring system with two carbonyl groups. 2-((R)-8-Oxo-2,3,6,7,8,9-hexahydro-1H-5-thia-9-aza-cyclohepta[f]inden-7-yl)-isoindole-1,3-dione is likely to be found in the realm of pharmaceuticals or as an intermediate in the synthesis of complex organic molecules, given its intricate structure and functional groups.
The CAS Registry Mumber 98413-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,1 and 3 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 98413-23: (7*9)+(6*8)+(5*4)+(4*1)+(3*3)+(2*2)+(1*3)=151 151 % 10 = 1 So 98413-23-1 is a valid CAS Registry Number.
