The chemical compound "2,2,4,6,6-Pentamethyl-1-oxo-2,6-dihydro-1H-1λ4-thia-2a,4,5a-triaza-cyclopropa[f]indene-3,5-dione" is a complex organic molecule with a unique structure. It features a cyclopropa[f]indene core, which is a tricyclic system with a cyclopropane ring fused to an indene. The molecule is characterized by the presence of a thiatriazacyclopropane ring, which contributes to its stability and reactivity. The compound is further defined by the presence of three carbonyl groups (dione) and a 1-oxo group, indicating the presence of a carbonyl group at the 1-position. The pentamethyl substitution pattern suggests that there are five methyl groups attached to the molecule, which can influence its physical properties such as boiling point, melting point, and solubility. 2,2,4,6,6-Pentamethyl-1-oxo-2,6-dihydro-1H-1λ4-thia-2a,4,5a-triaza-cyclopropa[f]indene-3,5-dione is likely to be of interest in the field of organic chemistry, potentially for its unique reactivity or as a building block in the synthesis of more complex molecules.
The CAS Registry Mumber 82613-75-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,6,1 and 3 respectively; the second part has 2 digits, 7 and 5 respectively. Calculate Digit Verification of CAS Registry Number 82613-75: (7*8)+(6*2)+(5*6)+(4*1)+(3*3)+(2*7)+(1*5)=130 130 % 10 = 0 So 82613-75-0 is a valid CAS Registry Number.
