The chemical compound "2-(3,4-Dimethyl-Δ^3-cyclopentenyl)-ethyl-4-nitro-benzenesulfonate" is a complex organic molecule with a unique structure. It features a cyclopentenyl ring, which is a five-membered ring with two methyl groups at the 3 and 4 positions, and a Δ^3 double bond. Attached to this ring is an ethyl group, which in turn is connected to a 4-nitro-benzenesulfonate group. The 4-nitro-benzenesulfonate moiety consists of a benzene ring with a nitro group at the 4 position and a sulfonate group attached to it. 2-<3.4-Dimethyl-Δ3-cyclopentenyl>-aethyl-<4-nitro-benzolsulfonat> is characterized by its aromatic and aliphatic components, making it a potentially versatile building block in organic synthesis, particularly in the preparation of pharmaceuticals and other specialty chemicals.
The CAS Registry Mumber 795-79-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,9 and 5 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 795-79: (5*7)+(4*9)+(3*5)+(2*7)+(1*9)=109 109 % 10 = 9 So 795-79-9 is a valid CAS Registry Number.
