Uridine, 5-bromo-5'-deoxy-5'-iodo-2',3'-O-(1-methylethylidene)- is a complex organic compound that belongs to the class of nucleosides. It is a derivative of uridine, a naturally occurring nucleoside composed of the base uracil and the sugar ribose. This specific compound features a 5-bromo-5'-deoxy-5'-iodo modification, which introduces a bromine atom at the 5-position and an iodine atom at the 5'-position of the ribose sugar, while also removing one oxygen atom from the sugar. Additionally, it has a 2',3'-O-(1-methylethylidene) group, which is a protecting group that shields the 2' and 3' hydroxyl groups of the ribose, preventing unwanted reactions at these sites. Uridine, 5-bromo-5'-deoxy-5'-iodo-2',3'-O-(1-methylethylidene)- is significant in the field of chemistry and biochemistry, particularly in the study of nucleic acid chemistry and the development of modified nucleosides for therapeutic applications.
The CAS Registry Mumber 94048-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,0,4 and 8 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 94048-48: (7*9)+(6*4)+(5*0)+(4*4)+(3*8)+(2*4)+(1*8)=143 143 % 10 = 3 So 94048-48-3 is a valid CAS Registry Number.
