Check Digit Verification of cas no
The CAS Registry Mumber 252554-79-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,5,5 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 252554-79:
(8*2)+(7*5)+(6*2)+(5*5)+(4*5)+(3*4)+(2*7)+(1*9)=143
143 % 10 = 3
So 252554-79-3 is a valid CAS Registry Number.

Pseudo-Prolines in Peptide Synthesis: Direct Insertion of Serine and Threonine Derived Oxazolidines in Dipeptides
Woehr, Torsten,Mutter, Manfred
, p. 3847 - 3848 (1995)
Dipeptides containing serine and threonine derived oxazolidines are prepared by reacting side chain unprotected dipeptides containing C-terminal Thr or Ser with dimethoxypropane.The resulting building blocks can be coupled in Fmoc-based solid phase peptide synthesis enhancing peptide solvation by its secondary structure disrupting potential.The present procedure may be considered as a first step towards a reversible modification of structural and functional properties of bioactive peptides and proteins.
