Check Digit Verification of cas no

The CAS Registry Mumber 81242-28-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,2,4 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 81242-28:
(7*8)+(6*1)+(5*2)+(4*4)+(3*2)+(2*2)+(1*8)=106
106 % 10 = 6
So 81242-28-6 is a valid CAS Registry Number.

SYNTHESIS OF NEW BRANCHED POLYPEPTIDES WITH POLY(LYSINE)BACK BONE

Hudecz, Ferenc,Szekerke, Maria

, p. 103 - 113 (2007/10/02)

New analogues of branched polypeptides were synthesised for a further, more detailed study of the influence of the side chain terminating amino acids, particularly the hydrophobic character, configuration and the number of these amino acids, on the conformation and biological properties of the polymers.The folowing amino acids were coupled to poly(L-Lys-(DL-Alam)) in suitably protected and activated forms to study the above mentioned aspects: L-Nle, L-Ile, L-Val, L-Phe, D-Phe, D-Leu, D-Tyr, D-His, L-Glu, D-Glu, L-Lys, D-Lys and additionally the L-Glu-L-Glu, D-Glu-D-Glu, L-Lys-L-Lys and D-Lys-D-Lys dipeptides.The protected and purified end products were freezedried and characterized by various methods.
