89028-37-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89028-37-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,2 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 89028-37:
(7*8)+(6*9)+(5*0)+(4*2)+(3*8)+(2*3)+(1*7)=155
155 % 10 = 5
So 89028-37-5 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.
