Uridine, 2-O-methyl-2',3'-O-(1-methylethylidene)-, also known as 2'-O-methyluridine, is a modified nucleoside derived from the natural nucleoside uridine. It is characterized by the presence of a methyl group at the 2' position of the ribose sugar and a 1-methylethylidene (isopropylidine) group bridging the 2' and 3' positions of the sugar moiety. This chemical modification can significantly alter the properties of the nucleoside, such as its stability, reactivity, and interaction with enzymes or other biomolecules. 2'-O-methyluridine is often used in the synthesis of modified nucleic acids, which have potential applications in molecular biology, drug development, and the study of RNA structure and function.
The CAS Registry Mumber 29507-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,5,0 and 7 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 29507-92: (7*2)+(6*9)+(5*5)+(4*0)+(3*7)+(2*9)+(1*2)=134 134 % 10 = 4 So 29507-92-4 is a valid CAS Registry Number.
