Check Digit Verification of cas no

The CAS Registry Mumber 289032-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,3 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 289032-98:
(8*2)+(7*8)+(6*9)+(5*0)+(4*3)+(3*2)+(2*9)+(1*8)=170
170 % 10 = 0
So 289032-98-0 is a valid CAS Registry Number.

Design, synthesis, and biological evaluation of N-Alkylated deoxynojirimycin (DNJ) derivatives for the treatment of dengue virus infection

We recently described the discovery of oxygenated N-alkyl deoxynojirimycin (DNJ) derivative 7 (CM-10-18) with antiviral activity against dengue virus (DENV) infection both in vitro and in vivo. This imino sugar was promising but had an EC50 against DENV in BHK cells of 6.5 μM, which limited its use in in vivo. Compound 7 presented structural opportunities for activity relationship analysis, which we exploited and report here. These structure-activity relationship studies led to analogues 2h, 2l, 3j, 3l, 3v, and 4b-4c with nanomolar antiviral activity (EC50 = 0.3-0.5 μM) against DENV infection, while maintaining low cytotoxicity (CC50 > 500 μM, SI > 1000). In male Sprague-Dawley rats, compound 3l was well tolerated at a dose up to 200 mg/kg and displayed desirable PK profiles, with significantly improved bioavailability (F = 92 α 4%).
