Z-D-Ala-D-Ala-NHNH-Boc is a synthetic peptide compound, consisting of a sequence of four amino acids: D-alanine, D-alanine, and two glycine residues, with a carbobenzyloxy (Cbz) protecting group. Z-D-Ala-D-Ala-NHNH-Boc is a precursor in the synthesis of certain antibiotics, such as vancomycin, which is used to treat bacterial infections. The Z group (benzyloxycarbonyl) is a temporary protecting group that shields the peptide bond from unwanted reactions during the synthesis process, while the Boc group (tert-butoxycarbonyl) protects the amino group. The compound plays a crucial role in pharmaceutical research and development, particularly in the production of semi-synthetic antibiotics derived from natural products.
The CAS Registry Mumber 27454-33-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,4,5 and 4 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 27454-33: (7*2)+(6*7)+(5*4)+(4*5)+(3*4)+(2*3)+(1*3)=117 117 % 10 = 7 So 27454-33-7 is a valid CAS Registry Number.
