Check Digit Verification of cas no

The CAS Registry Mumber 1240081-12-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,0,8 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1240081-12:
(9*1)+(8*2)+(7*4)+(6*0)+(5*0)+(4*8)+(3*1)+(2*1)+(1*2)=92
92 % 10 = 2
So 1240081-12-2 is a valid CAS Registry Number.

Recombination of diterpenoid structure units: Synthesis of antitumor amides bearing functionalized bicyclo[3.2.1]octane ring

Mao, Zewei,Li, Yan,Chen, Jingbo,Wang, Yuanyuan,Zhang, Hongbin

scheme or table, p. 4116 - 4119 (2010/08/07)

In this work, 23 new amides (14-36) bearing a representative diterpenoid structure unit, the functionalized bicyclo[3.2.1]octane ring, have been synthesized and its antitumor potential is studied. In vitro studies demonstrate that a number of amides with the bicyclo[3.2.1]oct-3-en-2-one subunit are active against HL-60, SMMC-7721, A-549, SK-BR-3, and PANC-1 tumor cell lines. The hybrid derivative, compound 20, was found to be the most potent compound (IC50 = 1.05 μM against HL-60) and more active than cisplatin (DDP), the positive control. Additionally, compound 20 exhibited broad spectrum in vitro anticancer activity with IC50 values of 1.1-4.3 μM against the five tested cancer cell lines.
