Check Digit Verification of cas no

The CAS Registry Mumber 1281816-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,1,8,1 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1281816-34:
(9*1)+(8*2)+(7*8)+(6*1)+(5*8)+(4*1)+(3*6)+(2*3)+(1*4)=159
159 % 10 = 9
So 1281816-34-9 is a valid CAS Registry Number.

Synthesis and biological evaluation of licofelone derivatives as anticancer and anti-inflammatory agents

Liu, Wukun,Zhou, Jinpei,Zhang, Huibin,Qian, Hai,Yin, Jiahan,Bensdorf, Kerstin,Gust, Ronald

, p. 911 - 917 (2012/07/03)

Two C5-substituted licofelone derivatives were developed and investigated for cytotoxicity against mammary (MCF-7 and MDA-MB 231) as well as colon carcinoma (HT-29) cancer cells. Both compounds were at least 2-fold more active than 5-fluorouracil (5-FU) and licofelone against mammary carcinoma cells. At HT-29 cells, they were less active, but nevertheless distinctly as active as 5-FU and still 2-fold more active than licofelone. However, variation of the C5- carboxylic group results in an occasionally remarkable decrease of anti-inflammatory potency in in vitro and in vivo.
