The chemical compound "(4aS)-6-isopropylidene-4c,4a-dimethyl-(4ar)-4,4a,5,6,7,8-hexahydro-3H-naphthalen-2-one-(2,4-dinitro-phenylhydrazone)" is a complex organic molecule with a unique structure. It features a hexahydro-naphthalen-2-one core, which is a type of cyclic hydrocarbon with six hydrogen atoms attached to the carbon atoms in the ring structure. The compound is characterized by an isopropylidene group at the 6-position, which is a three-carbon chain that forms a bridge between two carbon atoms. Additionally, it has two methyl groups attached to the 4c and 4a positions, contributing to its branched structure. The molecule is further defined by the presence of a 2,4-dinitro-phenylhydrazone group, which is a derivative of a phenylhydrazine molecule with two nitro groups at the 2 and 4 positions. This group is known for its reactivity and is often used in chemical analysis and synthesis. Overall, (4aS)-6-isopropylidene-4c,4a-dimethyl-(4ar)-4,4a,5,6,7,8-hexahydro-3H-naphthalen-2-one-(2,4-dinitro-phenylhydrazone) is a sophisticated example of organic chemistry, with potential applications in various fields due to its specific structural features.
The CAS Registry Mumber 6211-42-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,1 and 1 respectively; the second part has 2 digits, 4 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6211-42: (6*6)+(5*2)+(4*1)+(3*1)+(2*4)+(1*2)=63 63 % 10 = 3 So 6211-42-3 is a valid CAS Registry Number.
