Check Digit Verification of cas no

The CAS Registry Mumber 53100-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,1,0 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53100-44:
(7*5)+(6*3)+(5*1)+(4*0)+(3*0)+(2*4)+(1*4)=70
70 % 10 = 0
So 53100-44-0 is a valid CAS Registry Number.

Synthetic approaches to peptides containing the l-Gln-l-Val-D(S)-Dmt motif

Suaifan, Ghadeer A.R.Y.,Arafat, Tawfiq,Threadgill, Michael D.

, p. 3474 - 3488 (2008/02/05)

The pseudoprolines S-Dmo (5,5-dimethyl-4-oxaproline) and R-Dmt (5,5-dimethyl-4-thiaproline) have been used to study the effects of forcing a fully cis conformation in peptides. Synthesis of peptides containing these (which have the same configuration as l-Pro) is straightforward. However, synthesis of peptides containing S-Dmt is difficult, owing to the rapid cyclisation of l-Aaa-S-Dmt amides and esters to form the corresponding diketopiperazines (DKP); thus the intermediacy of l-Aaa-S-Dmt amides and esters must be avoided in the synthetic sequence. Peptides containing the l-Gln-l-Val-D(S)-Dmt motif are particularly difficult, owing to the insolubility of coupling partners containing Gln. Introduction of Gln as N-Boc-pyroglutamate overcame the latter difficulty and the dipeptide active ester BocPygValOC6F5 coupled in good yield with S-DmtOH. BocPygVal-S- DmtNH(CH2)2C6H4NO2 was converted quantitatively to BocGlnVal-S-DmtNH(CH2)2C6H4NO2 with ammonia, demonstrating the utility of this approach. Two peptide derivatives (CbzSerLysLeuGlnVal-S-DmtNH(CH2)2C6H4NO2 and CbzSerSerLysLeuGlnVal-S- DmtNH(CH2)2C6H4NO2) were assembled, using these new methods of coupling a dipeptide acid active ester with S-DmtOH and introduction of Gln as Pyg, followed by conventional peptide couplings. The presence of the Val caused these peptides to be cleaved very slowly by prostate-specific antigen (PSA) at Leu ↓ Gln, rather than the expected Gln ↓ Val.

Stereospecific synthesis of (2S,4R)-[5,5,5-2H3]leucine

August, Ryan A.,Khan, Jeffrey A.,Moody, Claire M.,Young, Douglas W.

, p. 507 - 514 (2007/10/03)

The first stereospecific chemical synthesis of a sample of the amino acid (2S)-leucine labelled in one of the diastereotopic methyl groups has been achieved using (2S)-pyroglutamic acid as a chiral template. This has been used to develop a method for assigning resonances to the diastereotopic methyl groups of the leucine residues in the 1H NMR spectra of proteins.
