H-Gln-O-Bu^t, also known as tert-butyloxycarbonyl-glutamine, is a chemical compound that serves as a protecting group in peptide synthesis. It is a derivative of glutamine, an amino acid, where the side chain amide group is protected by a tert-butyloxycarbonyl (Boc) group. This protection is crucial for preventing unwanted side reactions during the synthesis of peptides, particularly when using the Boc-SPPS (solid-phase peptide synthesis) method. The Boc group can be selectively removed under mild acidic conditions, allowing for the subsequent coupling of the next amino acid in the peptide chain. H-Gln-O-Bu^t is a key component in the stepwise assembly of peptides, ensuring that the glutamine residue is incorporated correctly and without premature reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 5132-46-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,3 and 2 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5132-46:
(6*5)+(5*1)+(4*3)+(3*2)+(2*4)+(1*6)=67
67 % 10 = 7
So 5132-46-7 is a valid CAS Registry Number.
