Check Digit Verification of cas no

The CAS Registry Mumber 909487-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,9,4,8 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 909487-75:
(8*9)+(7*0)+(6*9)+(5*4)+(4*8)+(3*7)+(2*7)+(1*5)=218
218 % 10 = 8
So 909487-75-8 is a valid CAS Registry Number.

New cyclic somatostatin analogues containing a pyrazinone ring: Importance of Tyr for antiproliferative activity

Miyazaki, Anna,Tsuda, Yuko,Fukushima, Shoji,Yokoi, Toshio,Vantus, Tibor,Boekoenyi, Gyoengyi,Szabo, Edit,Horvath, Aniko,Keri, Gyoergy,Okada, Yoshio

Novel somatostatin analogues containing a pyrazinone ring, compounds 1 and 2, exhibited good antiproliferative activity on A431 tumor cells. To increase antitumor activity and binding affinity on somatostatin receptors (SSTRs), we substituted Tyr in the critical sequence, Tyr-d-Trp-Lys, with more hydrophobic aromatic residue. The substituted compounds dramatically lost antitumor activity, indicating that Tyr residue was an essential residue.
