RiboNucleic Acid, commonly known as RNA, is a crucial biomolecule found in all living organisms, playing a significant role in various cellular processes. Composed of nucleotides containing ribose sugar, phosphate, and one of four nitrogenous bases (adenine, uracil, cytosine, and guanine), RNA is involved in protein synthesis, gene regulation, and acts as a catalyst in certain biochemical reactions. It is single-stranded and more flexible than its double-stranded counterpart, DNA, allowing it to adopt various structures to perform its functions. RNA is essential for decoding genetic information from DNA, facilitating the production of proteins, and maintaining the overall integrity of the genetic code.
The CAS Registry Mumber 9009-85-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,0 and 9 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 9009-85: (6*9)+(5*0)+(4*0)+(3*9)+(2*8)+(1*5)=102 102 % 10 = 2 So 9009-85-2 is a valid CAS Registry Number.
