2',4'-Dinitro-benzol-(1'-azo-3)-Δ1,3,5(10)-oestratrien is a complex organic compound with the molecular formula C18H12N2O4. It is characterized by a benzene ring substituted with two nitro groups at the 2' and 4' positions, and an azo group (-N=N-) connecting the benzene ring to a Δ1,3,5(10)-oestratrien moiety. 2',4'-Dinitro-benzol-(1'-azo-3)-Δ1,3,5(10)-oestratrien is a derivative of estradiol, a naturally occurring estrogen hormone, with the addition of a nitrobenzene azo group. It is likely used in research settings to study the effects of structural modifications on the biological activity of estrogens. Due to its complex structure and potential biological activity, it is important to handle 2',4'-Dinitro-benzol-(1'-azo-3)-Δ1,3,5(10)-oestratrien with care, following appropriate safety protocols.
The CAS Registry Mumber 6561-96-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,6 and 1 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6561-96: (6*6)+(5*5)+(4*6)+(3*1)+(2*9)+(1*6)=112 112 % 10 = 2 So 6561-96-2 is a valid CAS Registry Number.
