Z-Ala-Gly-Glykolsaeure-pentamethylbenzylester, also known as Z-Ala-Gly-Gly-OH pentamethylbenzyl ester, is a synthetic peptide derivative consisting of three amino acids: alanine (Ala), glycine (Gly), and glycine (Gly), with a pentamethylbenzyl ester group attached to the carboxylic acid group. Z-Ala-Gly-Glykolsaeure-pentamethylbenzylester is often used in peptide synthesis as a protected intermediate, where the Z group (benzyloxycarbonyl) serves as a protecting group for the amino group, and the pentamethylbenzyl ester group protects the carboxylic acid group. The protection of these functional groups is crucial for preventing unwanted side reactions during peptide synthesis, allowing for the controlled formation of peptide bonds. Once the peptide is synthesized, the protecting groups can be removed under specific conditions to yield the desired peptide sequence.

19648-42-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19648-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,4 and 8 respectively; the second part has 2 digits, 4 and 2 respectively.Calculate Digit Verification of CAS Registry Number 19648-42:
(7*1)+(6*9)+(5*6)+(4*4)+(3*8)+(2*4)+(1*2)=141
141 % 10 = 1
So 19648-42-1 is a valid CAS Registry Number.
