Check Digit Verification of cas no

The CAS Registry Mumber 1637569-04-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,7,5,6 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1637569-04:
(9*1)+(8*6)+(7*3)+(6*7)+(5*5)+(4*6)+(3*9)+(2*0)+(1*4)=200
200 % 10 = 0
So 1637569-04-0 is a valid CAS Registry Number.

Synthesis and anti-influenza activities of novel baicalein analogs

Chung, Shu-Ting,Chien, Pei-Yu,Huang, Wen-Hsin,Yao, Chen-Wen,Lee, An-Rong

, p. 415 - 421 (2014/05/20)

A series of novel flavones derivatives were synthesized based on modification of the active ingredients of a traditional Chinese medicine Scutellaria baicalensis GEORGI and screened for anti-influenza activity. The synthetic baicalein (flavone) analogs, especially with the B-rings substituted with bromine atoms, were much more potent than oseltamivir or ribavirin against H1N1 Tamiflu-resistant (H1N1 TR) virus and usually with more favorable selectivity. The most promising were 5b, 5c, 6b and 6c, all displaying an 50% effective concentration (EC50) at around 4.0-4.5 μM, and a selective index (SI=50% cytotoxic concentration (CC50)/EC 50)>70. For seasonal H3N2-infected influenza virus, both 5a and 5b with SI >17.3 indicated superior to ribavirin. The flavonoids having both not-naturally-occurring bromo-substituted B-rings and appropriate hydroxyls positioning on the A-rings might be critical in determining the activity and selectivity against H1N1-Tamiflu-resistant infected influenza viruses.
