1-(2-deoxy-3,5-di-O-p-toluyl-α-D-ribofuranosyl)-5-fluorouracil is a complex organic compound that serves as a modified nucleoside. It is characterized by the presence of a 5-fluorouracil (5-FU) base, which is a well-known antineoplastic and antimetabolite drug used in cancer chemotherapy. The compound features a 2-deoxy-D-ribose sugar moiety, which is essential for its interaction with cellular enzymes and incorporation into RNA. The 3,5-di-O-p-toluyl protecting groups are added to the ribose sugar to enhance the stability and solubility of the compound, making it more suitable for pharmaceutical applications. This chemical structure plays a crucial role in the compound's ability to inhibit thymidylate synthase, a key enzyme in DNA synthesis, thereby disrupting the proliferation of cancer cells.
The CAS Registry Mumber 2907-25-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 7 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2907-25: (6*2)+(5*9)+(4*0)+(3*7)+(2*2)+(1*5)=87 87 % 10 = 7 So 2907-25-7 is a valid CAS Registry Number.
