"O2',O3'-(2,4-dimethoxy-benzylidene)-cytidine" is a complex organic compound that belongs to the class of cytidine derivatives. Cytidine is a nucleoside, which is a building block of RNA, consisting of a cytosine base attached to a ribose sugar. In this specific compound, the cytidine molecule is modified by the addition of a 2,4-dimethoxy-benzylidene group, which is a benzene ring with two methoxy groups (-OCH3) at the 2nd and 4th positions, and a double bond (-C=O) connecting it to the 2' and 3' positions of the ribose sugar. This modification can alter the chemical properties and potential biological activities of the cytidine molecule, making it a subject of interest in chemical and pharmaceutical research. The compound may be used in studies related to nucleic acid chemistry, drug development, or as a research tool to understand the interactions of modified nucleosides with enzymes and other biomolecules.
The CAS Registry Mumber 2500-73-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,0 and 0 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 2500-73: (6*2)+(5*5)+(4*0)+(3*0)+(2*7)+(1*3)=54 54 % 10 = 4 So 2500-73-4 is a valid CAS Registry Number.
