Check Digit Verification of cas no

The CAS Registry Mumber 1210819-43-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,8,1 and 9 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1210819-43:
(9*1)+(8*2)+(7*1)+(6*0)+(5*8)+(4*1)+(3*9)+(2*4)+(1*3)=114
114 % 10 = 4
So 1210819-43-4 is a valid CAS Registry Number.

Anti-dengue-virus activity and structure-activity relationship studies of lycorine derivatives

Wang, Peng,Li, Lin-Feng,Wang, Qing-Yin,Shang, Lu-Qing,Shi, Pei-Yong,Yin, Zheng

, p. 1522 - 1533 (2014/07/21)

Dengue is a systemic viral infection that is transmitted to humans by Aedes mosquitoes. No vaccines or specific therapeutics are currently available for dengue. Lycorine, which is a natural plant alkaloid, has been shown to possess antiviral activities against flaviviruses. In this study, a series of novel lycorine derivatives were synthesized and assayed for their inhibition of dengue virus (DENV) in cell cultures. Among the lycorine analogues, 1-acetyllycorine exhibited the most potent anti-DENV activity (EC50=0.4 μM) with a reduced cytotoxicity (CC50>300 μM), which resulted in a selectivity index (CC50/EC50) of more than 750. The ketones 1-acetyl-2-oxolycorine (EC50=1.8 μM) and 2-oxolycorine (EC50=0.5 μM) also exhibited excellent antiviral activities with low cytotoxicity. Structure-activity relationships for the lycorine derivatives against DENV are discussed. A three-dimensional quantitative structure-activity relationship model was established by using a comparative molecular-field analysis protocol in order to rationalize the experimental results. Further modifications of the hydroxy group at the C1 position with retention of a ketone at the C2 position could potentially lead to inhibitors with improved overall properties. Alkaloids that bite back: Dengue is a systemic viral infection that is transmitted to humans by Aedes mosquitoes. Currently, vaccines or specific therapeutics are not available. Lycorine, which is a natural alkaloid, has reportedly demonstrated biological activity against dengue virus (DENV). A series of lycorine derivatives and their anti-DENV activities are reported herein.
