Check Digit Verification of cas no
The CAS Registry Mumber 97251-06-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,2,5 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97251-06:
(7*9)+(6*7)+(5*2)+(4*5)+(3*1)+(2*0)+(1*6)=144
144 % 10 = 4
So 97251-06-4 is a valid CAS Registry Number.

SYNTHESIS AND NMR INVESTIGATION OF CYCLIC PENTAPEPTIDE ANALOGUES OF THYMOPENTIN
Kessler, Horst,Kutscher, Bernhard
, p. 177 - 180 (2007/10/02)
The synthesis of two cyclic pentapeptides cyclo(-Arg-Lys-Xxx-D-Val-Tyr-) (Xxx= Asp or Glu) with thymopentin-analogue sequences is described.Cyclization was achieved by the carbodiimide/DMAP method.The results of the NMR investigations performed on the pro
