"Z-Gly-Leu-Lys(-Z)-OCH2Ph" is a peptide compound consisting of four amino acids: glycine (Gly), leucine (Leu), and lysine (Lys), with the latter having a benzyl group attached to it. The "Z" groups are protecting groups used in peptide synthesis to prevent unwanted side reactions. The "OCH2Ph" part indicates that the peptide is linked to a phenyl group through an ethylene (-CH2-) bridge. Z-Gly-Leu-Lys(-Z)-OCH2Ph is typically used in the field of organic chemistry and peptide synthesis, where the protecting groups are crucial for controlling the reactivity of the peptide bonds and ensuring the correct sequence of amino acids is formed. The final product can be used in various applications, such as drug development, where specific peptide sequences are required for biological activity.

Check Digit Verification of cas no

The CAS Registry Mumber 70290-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,2,9 and 0 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 70290-83:
(7*7)+(6*0)+(5*2)+(4*9)+(3*0)+(2*8)+(1*3)=114
114 % 10 = 4
So 70290-83-4 is a valid CAS Registry Number.

THE DEPENDENCE OF ASYMMETRIC INDUCTION ON SOLVENT POLARITY AND TEMPERATURE IN PEPTIDE SYNTHESIS

Benoiton, N. Leo,Kuroda, K.,Chen, F. M. F.

, p. 3361 - 3364 (2007/10/02)

When a racemic 2,4-dialkyl-5(4H)-oxazolone reacts with an L-amino acid ester, the D-L epimer is formed in excess in apolar solvents and the L-L epimer is formed in excess in polar solvents, the proportion of L-L isomer increasing with decreasing temperature.
