Z-Val-Glykolsaeure-pentamethylbenzylester, also known as Z-Val-Gly-O-PMB, is a synthetic peptide compound consisting of three amino acids: valine (Val), glycine (Gly), and a protected serine residue (Ser). The "Z" group is a protecting group for the amino group of the valine, while the "PMB" (pentylmethylbenzyl) group is a protecting group for the hydroxyl group of the serine. Z-Val-Glykolsaeure-pentamethylbenzylester is commonly used in peptide synthesis as a building block for the construction of larger peptides and proteins. The protecting groups ensure that the amino and hydroxyl groups remain unreacted during the synthesis process, allowing for controlled coupling of amino acids to form the desired peptide sequence. Once the peptide is fully synthesized, the protecting groups can be removed to reveal the final product with its natural amino acid side chains.

Check Digit Verification of cas no

The CAS Registry Mumber 19601-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,6,0 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19601-23:
(7*1)+(6*9)+(5*6)+(4*0)+(3*1)+(2*2)+(1*3)=101
101 % 10 = 1
So 19601-23-1 is a valid CAS Registry Number.
