Check Digit Verification of cas no

The CAS Registry Mumber 928138-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,1,3 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 928138-25:
(8*9)+(7*2)+(6*8)+(5*1)+(4*3)+(3*8)+(2*2)+(1*5)=184
184 % 10 = 4
So 928138-25-4 is a valid CAS Registry Number.

, p. 2091 - 2095 (2008/02/02)

In order to explore the range of biological activities of the podophyllotoxin compound class, a novel series of derivatives of podophyllotoxin, which were conjugates containing stavudine and different structural podophyllotoxin analogues, were designed, synthesized, and evaluated for their anti-HIV-1 activities in vitro. Among these compounds, 19d and 19c showed the highest anti-HIV-1 activities with EC50 values of 0.17 and 0.29 μM and TI values of 466.9 and 354.5, respectively.
