53665-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 53665-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,6,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53665-99:
(7*5)+(6*3)+(5*6)+(4*6)+(3*5)+(2*9)+(1*9)=149
149 % 10 = 9
So 53665-99-9 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.
