2-C-hydroxymethyl-D-ribonic acid, also known as 2-deoxy-D-ribose-5-phosphate or simply 2-deoxy-D-ribose, is a monosaccharide that plays a crucial role in the synthesis of DNA. It is structurally similar to D-ribose, but with a hydrogen atom replacing the 2'-hydroxyl group, making it a 2-deoxy sugar. This chemical is an important intermediate in the pentose phosphate pathway, a metabolic pathway that generates NADPH, a key reducing agent in cellular respiration and biosynthesis. Additionally, 2-deoxy-D-ribose is a precursor in the synthesis of thymidine, a nucleoside that is essential for the formation of DNA. Its unique structure contributes to the stability and function of DNA, as it lacks the hydroxyl group that would otherwise form a glycosidic bond with the phosphate backbone, thus preventing the sugar-phosphate backbone from breaking down.
The CAS Registry Mumber 469-09-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 9 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 469-09: (5*4)+(4*6)+(3*9)+(2*0)+(1*9)=80 80 % 10 = 0 So 469-09-0 is a valid CAS Registry Number.
