Check Digit Verification of cas no

The CAS Registry Mumber 892440-74-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,2,4,4 and 0 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 892440-74:
(8*8)+(7*9)+(6*2)+(5*4)+(4*4)+(3*0)+(2*7)+(1*4)=193
193 % 10 = 3
So 892440-74-3 is a valid CAS Registry Number.

Synthesis and biological activity of novel 1-(2,3,4-trimethoxyphenyl)-2- {[5-(3,4,5-trimethoxyphenyl)-1,3,4-thiadiazol-2-yl]thio}ethanone oxime ester derivatives

, p. 867 - 871 (2006)

In a search for new fungicide and anticancer agent with improved biological properties and different bioactivity spectrum, we designed and synthesized a series of novel oxime esters containing 1,3,4-thiadiazole group in moderate yield starting from gallic acid. The title compounds were identified by IR, 1H NMR, 13C NMR and elemental analysis. The bioassay tests showed that these title compounds exhibit weak to moderate anticancer activity in vitro by MTT method.
