Gly-Gly-ONB*HBr, also known as N-(9-fluorenylmethoxycarbonyl)-glycyl-glycine hydrobromide, is a synthetic peptide building block used in solid-phase peptide synthesis. It consists of two glycine amino acids linked together, with a 9-fluorenylmethoxycarbonyl (Fmoc) protecting group attached to the N-terminus and a 2-nitrobenzyl (ONB) protecting group on the side chain of the second glycine. The hydrobromide salt form of the compound facilitates its solubility in water. This chemical is crucial for the step-by-step assembly of peptides, as it allows for the controlled addition of amino acids to a growing peptide chain. The Fmoc group is used for protecting the amino terminus during synthesis, while the ONB group protects the side chain, ensuring that only the desired peptide bonds are formed. Once the peptide synthesis is complete, the protecting groups can be removed to reveal the final peptide product.

Check Digit Verification of cas no

The CAS Registry Mumber 6867-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,6 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6867-99:
(6*6)+(5*8)+(4*6)+(3*7)+(2*9)+(1*9)=148
148 % 10 = 8
So 6867-99-8 is a valid CAS Registry Number.
