"N-(N-benzyloxycarbonyl-glycyl)-glycine-(4-nitro-benzyl ester)" is a complex organic compound with the molecular formula C22H22N2O8. It is a derivative of glycine, an amino acid, and features a benzyloxycarbonyl (Z) protecting group on the N-terminal glycine residue and a 4-nitrobenzyl ester group on the C-terminal glycine. N-(N-benzyloxycarbonyl-glycyl)-glycine-(4-nitro-benzyl ester) is often used in peptide synthesis as a protected building block, where the protecting groups can be removed under specific conditions to facilitate the formation of peptide bonds. The benzyloxycarbonyl group protects the amino group from unwanted reactions, while the 4-nitrobenzyl ester group protects the carboxyl group. The compound's structure allows for controlled peptide bond formation in the synthesis of larger peptides and proteins.

Check Digit Verification of cas no

The CAS Registry Mumber 3916-37-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3916-37:
(6*3)+(5*9)+(4*1)+(3*6)+(2*3)+(1*7)=98
98 % 10 = 8
So 3916-37-8 is a valid CAS Registry Number.

Vibrational spectra of N-acetylglycine oligomers. Part 2. - Raman scattering study of selectively C-deuteriated oligomers with polyglycine I- and II-type structures

Etori, Hideki,Taga, Keijiro,Okabayashi, Hirofumi,Ohshima, Kunihiro

, p. 313 - 319 (2007/10/03)

Selectively C-deuteriated N-acetylglycine trimer and tetramer acid types have been synthesized, and their two crystalline modifications, solid-A and solid-B [which correspond in structure to polyglycine (PG) II and I, respectively] have been prepared. Raman scattering spectra have been measured for a series of these glycine oligomers, and the CH2- and CD2-characteristic modes have been investigated in detail. Assignment of the CH2-characteristic bands to each CH2 group in the oligomers has been carried out successfully. In particular, the results obtained from the CD2 stretch region show that N- and C-terminal glycine residues for the PGI- and PGII-type trimers and tetramers are all in very similar environments and that the glycine residues which are sandwiched between the two terminal residues are also in a similar environment for both the trimers and the tetramers.
