1,2,3,5-tetra-O-acetyl-4-thio-D-ribofuranose is a complex organic compound that plays a significant role in the field of biochemistry and pharmaceuticals. 1,2,3,5-tetra-O-acetyl-4-thio-D-ribofuranose is a derivative of D-ribofuranose, a sugar component found in RNA and DNA, with four acetyl groups attached to the hydroxyl groups at positions 1, 2, 3, and 5, and a sulfur atom replacing the oxygen atom at position 4. The presence of the sulfur atom makes it a thio-sugar, which is an important class of compounds in the synthesis of various nucleoside analogs and other biologically active molecules. The acetyl groups protect the hydroxyl groups during chemical reactions, allowing for selective functionalization and modification of the molecule. 1,2,3,5-tetra-O-acetyl-4-thio-D-ribofuranose is widely used in the synthesis of antiviral and anticancer drugs, as well as in the study of carbohydrate chemistry and glycobiology.
The CAS Registry Mumber 2495-74-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,9 and 5 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2495-74: (6*2)+(5*4)+(4*9)+(3*5)+(2*7)+(1*4)=101 101 % 10 = 1 So 2495-74-1 is a valid CAS Registry Number.
