The term "3'-oxo-" refers to a specific chemical structure found in certain organic compounds, particularly in the context of nucleosides and nucleotides. In this structure, the "3'" indicates the position of the modification on the sugar ring, which is the backbone of these molecules. The "oxo" part signifies the presence of a carbonyl group (C=O), which is a double-bonded oxygen to a carbon atom. This functional group is crucial for the reactivity and biological activity of the molecule. In nucleosides and nucleotides, the 3'-oxo- modification is often involved in the formation of phosphodiester bonds, which link the nucleotides together in DNA and RNA, and it plays a key role in the energy transfer and enzymatic reactions within cells. The 3'-oxo- structure is also significant in the context of drug design, as it can influence the binding affinity and specificity of molecules interacting with biological targets.
The CAS Registry Mumber 5838-88-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,3 and 8 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5838-88: (6*5)+(5*8)+(4*3)+(3*8)+(2*8)+(1*8)=130 130 % 10 = 0 So 5838-88-0 is a valid CAS Registry Number.
