Check Digit Verification of cas no

The CAS Registry Mumber 446044-18-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,6,0,4 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 446044-18:
(8*4)+(7*4)+(6*6)+(5*0)+(4*4)+(3*4)+(2*1)+(1*8)=134
134 % 10 = 4
So 446044-18-4 is a valid CAS Registry Number.

Synthesis and cytotoxicity of 3,4-diaryl-2(5H)-furanones

Kim, Yong,Nam, Nguyen-Hai,You, Young-Jae,Ahn, Byung-Zun

, p. 719 - 722 (2007/10/03)

A series of 3,4-diaryl-2(5H)-furanone derivatives were synthesized and evaluated for their cytotoxicity in a small panel of cancer cell lines. Four out of 10 compounds in this series, for example 3-(3,4,5-trimethoxyphenyl)-4-(4-methoxyphenyl)-, 3-(3,4,5-trimethoxyphenyl)-4-(3-hydroxy-4-methoxyphenyl)-, 3-(3,4,5-trimethoxyphenyl)-4-(3-amino-4-methoxyphenyl)-, and 3-(3,4,5-trimethoxyphenyl)-4-(2-naphthyl)-2(5H)-furanones, were found to have potent cytotoxic activities with ED50values of less than 20 nM in most of the cell lines tested.
