1-Ethyl-3,3-dimethyl-1,3-dihydro-spiro[indole-2,2'-pyrano[3,2-h]quinoline] is a complex organic compound characterized by a unique molecular structure. It features a spiro arrangement, which means it has two rings sharing a common atom. In this case, the two rings are an indole and a pyranoquinoline. The indole ring is substituted with an ethyl group at the 1-position and two methyl groups at the 3-position. The pyranoquinoline ring is fused to the indole, creating a spiro junction. 1-ethyl-3,3-dimethyl-1,3-dihydro-spiro[indole-2,2'-pyrano[3,2-h]quinoline] is a member of the spiro compounds class and is known for its potential applications in pharmaceuticals and materials science due to its specific chemical properties and structural features.
The CAS Registry Mumber 3879-66-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,7 and 9 respectively; the second part has 2 digits, 6 and 6 respectively. Calculate Digit Verification of CAS Registry Number 3879-66: (6*3)+(5*8)+(4*7)+(3*9)+(2*6)+(1*6)=131 131 % 10 = 1 So 3879-66-1 is a valid CAS Registry Number.
