52071-69-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52071-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,7 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52071-69:
(7*5)+(6*2)+(5*0)+(4*7)+(3*1)+(2*6)+(1*9)=99
99 % 10 = 9
So 52071-69-9 is a valid CAS Registry Number.

Total synthesis and biological potential of psammosilenin A
Dahiya, Rajiv
experimental part, p. 502 - 509 (2009/04/04)
The present work reports the synthesis of a plant-originated cyclooctapeptide - psammosilenin A 8 by cyclization of linear peptide fragment phe-pro-phe-phe-ala-pro-leu-pro-Opfp which was prepared by coupling of tetrapeptide units Boc-phe-pro-phe-phe-OH an
