142342-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142342-87-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,3,4 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 142342-87:
(8*1)+(7*4)+(6*2)+(5*3)+(4*4)+(3*2)+(2*8)+(1*7)=108
108 % 10 = 8
So 142342-87-8 is a valid CAS Registry Number.

Formation of oxazolines and thiazolines in peptides by the Mitsunobu reaction
Galeotti,Montagne,Poncet,Jouin
, p. 2807 - 2810 (2007/10/02)
The Mitsunobu reaction was efficiently used to introduce oxazolines and thiazolines in the peptide backbone. The reaction proceeded from β-hydroxy α-amino acid-containing peptides at room temperature in 58-72% isolated yields.
