67368-23-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67368-23-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67368-23:
(7*6)+(6*7)+(5*3)+(4*6)+(3*8)+(2*2)+(1*3)=154
154 % 10 = 4
So 67368-23-4 is a valid CAS Registry Number.

Reduction of methionine sulfoxide with NH4I/TFA: Compatibility with peptides containing cysteine and aromatic amino acids

Vilaseca, Marta,Nicolas, Ernesto,Capdevila, Fina,Giralt, Ernest

, p. 15273 - 15286 (1998)

The reduction of methionine sulfoxide with ammonium iodide in trifluoroacetic acid has been studied in peptides containing cysteine, histidine, tyrosine or tryptophan residues. While histidine and tyrosine have proved to be stable under the experimental conditions, cysteine is oxidized to cystine and tryptophan dimerizes to form 2-indolylindolenine derivatives. The use of methyl sulfide to increase the reduction rate minimizes the problem and protection of indole ring with the formyl group avoids the side reaction for this amino acid.
