27169-27-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27169-27-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,1,6 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 27169-27:
(7*2)+(6*7)+(5*1)+(4*6)+(3*9)+(2*2)+(1*7)=123
123 % 10 = 3
So 27169-27-3 is a valid CAS Registry Number.

A Convenient Synthesis of Peptide Using Oxallates
Takeda, Kazuyoshi,Sawada, Izumi,Suzuki, Akira,Ogura, Haruo
, p. 4451 - 4454 (2007/10/02)
The equimolar reactions of N-protected amino acids , amino acids or amino acid esters with oxallates (1a-1e) having active ester groups in the presence of pyridine in acetonitrile afforded the corresponding dipeptides via active esters in good yields.
