The chemical compound "1-Benzyloxycarbonylamino-5,16-dihydroxy-26-(N-acetyl-hydroxylamino)-6,9,17,20-tetraoxo-5,10,16,21-tetraaza-hexaeikosan" is a complex organic molecule with a molecular formula that suggests it contains multiple functional groups, including hydroxyl (-OH), carbonyl (C=O), and amino (-NH2) groups. The presence of a benzyloxycarbonyl (Cbz) group indicates that it is likely a peptide or protein derivative, where this group is commonly used as a protecting group for amino groups. The compound also features a N-acetyl-hydroxylamino group, which is an acetylated hydroxylamine, suggesting it may have been modified to prevent unwanted reactions at the hydroxylamine group. The compound's structure is characterized by a hexa-eikosan backbone, which is a 21-carbon chain, and the presence of four oxygen atoms in the form of ketone groups (C=O) at positions 6, 9, 17, and 20, and two hydroxyl groups at positions 5 and 16. 1-Benzyloxycarbonylamino-5,16-dihydroxy-26-(N-acetyl-hydroxylamino)-6,9,17,20-tetraoxo-5,10,16,21-tetraaza-hexaeikosan is likely to be of interest in the field of biochemistry or medicinal chemistry, possibly as a precursor to a biologically active molecule or as a component in a drug synthesis process.
The CAS Registry Mumber 2518-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 8 respectively; the second part has 2 digits, 8 and 8 respectively. Calculate Digit Verification of CAS Registry Number 2518-88: (6*2)+(5*5)+(4*1)+(3*8)+(2*8)+(1*8)=89 89 % 10 = 9 So 2518-88-9 is a valid CAS Registry Number.
