Check Digit Verification of cas no

The CAS Registry Mumber 937389-80-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,3,8 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 937389-80:
(8*9)+(7*3)+(6*7)+(5*3)+(4*8)+(3*9)+(2*8)+(1*0)=225
225 % 10 = 5
So 937389-80-5 is a valid CAS Registry Number.

Structure-activity relationship studies of gonadotropin-releasing hormone antagonists containing S-aryl/alkyl norcysteines and their oxidized derivatives

Samant, Manoj P.,White, Richard,Hong, Doley J.,Croston, Glenn,Conn, P. Michael,Janovick, Jo Ann,Rivier, Jean

, p. 2067 - 2077 (2008/02/03)

A series of acyline analogues incorporating L- and D-isomers of S-arylated/alkylated norcysteines [Ncy(R), where R is 2-naphthyl, methyl, and isopropyl] at positions 1, 4, 7, and 10 were synthesized. Some of these analogues were mono- and dioxidized to sulfoxides and sulfones. All of the analogues of acyline were screened for the antagonism of the GnRH-induced response in a reporter gene assay in HEK-293 cells expressing the human GnRH receptor. Nine of the analogues (9, 11, 15, 16, 17, 19, 20, 21, and 22) had antagonistic potency (IC50 50 = 0.52 nM) in this assay. Selected analogues (9, 11, 15, 16, 19, and 21) were tested in vitro for their antagonism at the rat GnRH-R in a reporter gene assay as well as in an in vivo intact male rat assay. Analogues 9 and 15 were the most potent in suppressing testosterone levels.
