Z-D-Ala-D-Ala-OEt, also known as Carboxyethyl-D-Ala-D-Ala, is a synthetic tripeptide consisting of three amino acids: D-alanine, D-alanine, and D-alanine, with an ethyl ester group attached to the carboxylic acid end. Z-D-Ala-D-Ala-OEt is a key intermediate in the synthesis of various semi-synthetic beta-lactam antibiotics, such as penicillins and cephalosporins, which are widely used to treat bacterial infections. The Z group (benzyloxycarbonyl) is a protecting group that shields the N-terminal amino group during the synthesis process, allowing for selective modification of the peptide chain. Z-D-Ala-D-Ala-OEt plays a crucial role in the pharmaceutical industry, as it enables the production of modified antibiotics with improved properties, such as enhanced stability, broader-spectrum activity, and reduced side effects.

Check Digit Verification of cas no

The CAS Registry Mumber 79411-36-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,1 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 79411-36:
(7*7)+(6*9)+(5*4)+(4*1)+(3*1)+(2*3)+(1*6)=142
142 % 10 = 2
So 79411-36-2 is a valid CAS Registry Number.

Teramoto, Takero,Deguchi, Mikito,Kurosaki, Toshikazu,Okawara, Makoto

, p. 1109 - 1112 (2007/10/02)

Preparations of optically active N-hydroxytartrimides were achieved. 1,3,4-Trihydroxysuccinimide ester of Z-L-alanine and 1-hydroxy-3,4-diacetoxysuccinimide ester of Z-D-alanine were allowed to react with D,L-alaninate to produce L-L form and D-D form of
