Check Digit Verification of cas no

The CAS Registry Mumber 1258795-43-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,7,9 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1258795-43:
(9*1)+(8*2)+(7*5)+(6*8)+(5*7)+(4*9)+(3*5)+(2*4)+(1*3)=205
205 % 10 = 5
So 1258795-43-5 is a valid CAS Registry Number.

One-pot tandem copper-catalyzed library synthesis of 1-thiazolyl-1,2,3- triazoles as anticancer agents

experimental part, p. 72 - 78 (2011/04/17)

One-pot multicomponent synthesis to assemble compounds has been an efficient method for constructing a compound library. We have developed one-pot tandem copper-catalyzed azidation and CuAAC reactions that afford 1-thiazolyl-1,2,3-triazoles with anticancer activity. By utilizing this one-pot synthetic strategy, we constructed a library of 1-thiazolyl-1,2,3-triazoles in search of the potent lead compound. Furthermore, 1-thiazolyl-1,2,3-triazoles were evaluated for anticancer activity against the multidrug-resistant cancer cells MES-SA/Dx5. Most of the 1-thiazolyl-1,2,3-triazoles revealed cytotoxic effect against cancer cells at micromolar to low micromolar range. Testing some of the most potent compounds (5{4,2-4} and 5{5,1-3}) against the normal cell line Vero showed no significant toxicity (except 5{4,2}) to normal cells. This result indicates that compounds 5{4,3-4} and 5{5,1-3} possessed good potency and selectivity to cancer cells over normal cells.
