1-(2-deoxy-β-D-arabino-hexopyranosyl)uracil, also known as Thymine arabinoside or Thymidine, is a nucleoside analog consisting of a uracil base attached to a 2-deoxy-β-D-arabino-hexopyranose sugar moiety. 1-(2-deoxy-β-D-arabino-hexopyranosyl)uracil plays a crucial role in DNA synthesis, as it is a building block for the formation of DNA strands. Thymidine is a key component in the process of DNA replication, where it pairs with adenine to form the backbone of the DNA double helix. It is also used in various medical applications, such as antiviral and anticancer treatments, due to its ability to interfere with the replication of certain viruses and cancer cells. In summary, 1-(2-deoxy-β-D-arabino-hexopyranosyl)uracil is an essential nucleoside that contributes to the structure and function of DNA, with potential therapeutic applications in medicine.
The CAS Registry Mumber 5139-56-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,3 and 9 respectively; the second part has 2 digits, 5 and 6 respectively. Calculate Digit Verification of CAS Registry Number 5139-56: (6*5)+(5*1)+(4*3)+(3*9)+(2*5)+(1*6)=90 90 % 10 = 0 So 5139-56-0 is a valid CAS Registry Number.
