226907-93-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 226907-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,9,0 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 226907-93:
(8*2)+(7*2)+(6*6)+(5*9)+(4*0)+(3*7)+(2*9)+(1*3)=153
153 % 10 = 3
So 226907-93-3 is a valid CAS Registry Number.

Synthesis and biological evaluation of 2,8-disubstituted 9-benzyladenines: Discovery of 8-mercaptoadenines as potent interferon-inducers

Hirota, Kosaku,Kazaoka, Kazunori,Sajiki, Hironao

, p. 2715 - 2722 (2007/10/03)

Recently, we have identified 9-benzyl-8-hydroxyadenines bearing an appropriate substituent (a butoxy, propylthio or butylamino group) at the 2-position as potent interferon (IFN)-inducers. Herein we report the design, synthesis, and IFN-inducing activity of 8-substituted 9-benzyladenines possessing such an appropriate substituent at the 2-position. Introduction of the appropriate substituent into the 2-position of the adenine nucleus gave rise to expression of the activity even in 9-benzyladenines bearing no hydroxyl group at the 8-position. An amino group at the 6-position and a hydroxyl or thiol group carrying an acidic proton at the 8-position are required to express excellent IFN-inducing activity. 9-Benzyl-2-butoxy-8-mercaptoadenine (9) indicated the most potent activity with MEC of 0.001 μM.
