Check Digit Verification of cas no

The CAS Registry Mumber 405231-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,5,2,3 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 405231-20:
(8*4)+(7*0)+(6*5)+(5*2)+(4*3)+(3*1)+(2*2)+(1*0)=91
91 % 10 = 1
So 405231-20-1 is a valid CAS Registry Number.

Synthesis of halogen-substituted 3-deazaadenosine and 3-deazaguanosine analogues as potential antitumor/antiviral agents

Liu,Luo,Mozdziesz,Lin,Dutschman,Gullen,Cheng,Sartorelli

, p. 1975 - 2000 (2001)

Various 2-halogen-substituted analogues (38, 39, 43 and 44), 3-halogensubstituted analogues (51 and 52), and 2′,3′ -dihalogen- substituted analogues (57-60) of 3-deazaadenosine and 3-halogen-substituted analogues (61 and 62) of 3-deazaguanosine have been synthesized as potential anticancer and/or antiviral agents. Among these compounds, 3-deaza-3-bromoguanosine (62) showed significant cytotoxicity against L1210, P388, CCRF-CEM and B16F10 cell lines in vitro, producing IC50 values of 3, 7, 9 and 7μM, respectively. Several 3-deazaadenosine analogues (38, 51, 57 and 59) showed moderate to weak activity against hepatitis B virus.
