167319-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 167319-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,3,1 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 167319-89:
(8*1)+(7*6)+(6*7)+(5*3)+(4*1)+(3*9)+(2*8)+(1*9)=163
163 % 10 = 3
So 167319-89-3 is a valid CAS Registry Number.

Synthesis of fully protected (2R,3R,4S)-4-amino-7-guanidino-2,3-dihydroxy heptanoic acid

Yoshino, Ryo,Tokairin, Yoshinori,Konno, Hiroyuki

supporting information, p. 1604 - 1606 (2017/04/03)

(2R,3R,4S)-4-Amino-7-guanidino-2,3-dihydroxyheptanoic acid (AGDHE), a common constituent of biologically active marine peptides, callipeltin A (1) and neamphamide A, was synthesized as its orthogonally protected derivative from L-glutamic acid in 15 steps. Guanidination by the Mitsunobu condition and osmium-catalyzed dihydroxylation of the corresponding Z-olefin were employed as the key steps.

Promoting peptide α-helix formation with dynamic covalent oxime side-chain cross-links

Haney, Conor M.,Loch, Matthew T.,Horne, W. Seth

supporting information; experimental part, p. 10915 - 10917 (2011/11/06)

Covalent side-chain cross-linking has been shown to be a viable strategy to control peptide folding. We report here that an oxime side-chain linkage can elicit α-helical folds from peptides in aqueous solution. The bio-orthogonal bridge is formed rapidly

Design and concise synthesis of fully protected analogues of L-γ-carboxyglutamic acid

Jiang, Sheng,Li, Peng,Lai, Christopher C.,Kelley, James A.,Roller, Peter P.

, p. 7307 - 7314 (2007/10/03)

The design and synthesis of four nonnaturally occurring amino acid analogues of L-γ-carboxyglutamic acid (Gla), appropriately protected for Fmoc-based solid-phase peptide synthesis (SPPS), is described. These amino acids are Bu-Mal 2, BCAH 3, Pen-Mal 4, a
