57830-13-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57830-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,3 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 57830-13:
(7*5)+(6*7)+(5*8)+(4*3)+(3*0)+(2*1)+(1*3)=134
134 % 10 = 4
So 57830-13-4 is a valid CAS Registry Number.

S1P3-sparing S1P1 agonists have attracted attention as a suppressant of autoimmunity with reduced side effects. Our synthetic efforts and extensive SAR studies led to the discovery of 10b named CS-2100 with the EC50 value of 4.0 nM for human S1P1 and over 5000-fold selectivity against S1P3. The in vivo immunosuppressive efficacy was evaluated in rats on host versus graft reaction and the ID 50 value was determined at 0.407 mg/kg. The docking studies of CS-2100 with the homology model of S1P1 and S1P3 showed that the ethyl group on the thiophene ring of CS-2100 was sterically hindered by Phe263 in S1P3, not in the case of Leu276 in S1P1. This observation gives an explanation for the excellent S1P3-sparing characteristic of CS-2100.
