The chemical compound "2,2,4c,8c-tetramethyl-6-phenyl-(4ar,7ac)-4,4a,7a,8-tetrahydro-[1,3]dioxolo[4,5-f]isoindole-5,7-dione" is a complex organic molecule with a unique structure. It features a tetrahydro-[1,3]dioxolo[4,5-f]isoindole core, which is a fused ring system consisting of a dioxolane ring and an isoindole ring. The molecule is further characterized by the presence of four methyl groups (-CH3) at the 2, 2, 4c, and 8c positions, and a phenyl group (C6H5) attached to the 6 position. The compound also has a 4a, 7a, and 8-tetrahydro configuration, indicating the presence of four hydrogen atoms in these positions, which contribute to the molecule's overall stability and reactivity. The 5,7-dione functional groups suggest the presence of two carbonyl groups (C=O) at these positions, which are key to the compound's chemical properties and potential applications. This molecule's structure and properties make it a subject of interest in organic chemistry, potentially for its use in the synthesis of pharmaceuticals or other specialized applications.
The CAS Registry Mumber 70517-41-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,1 and 7 respectively; the second part has 2 digits, 4 and 1 respectively. Calculate Digit Verification of CAS Registry Number 70517-41: (7*7)+(6*0)+(5*5)+(4*1)+(3*7)+(2*4)+(1*1)=108 108 % 10 = 8 So 70517-41-8 is a valid CAS Registry Number.
