Check Digit Verification of cas no

The CAS Registry Mumber 1259017-53-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,0,1 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1259017-53:
(9*1)+(8*2)+(7*5)+(6*9)+(5*0)+(4*1)+(3*7)+(2*5)+(1*3)=152
152 % 10 = 2
So 1259017-53-2 is a valid CAS Registry Number.

Novel EGFR inhibitors prepared by combination of dithiocarbamic acid esters and 4-anilinoquinazolines

Li, Ri-Dong,Zhang, Xin,Li, Qiao-Yan,Ge, Ze-Mei,Li, Run-Tao

, p. 3637 - 3640 (2011/08/06)

On the basis of combination strategy, a novel series of EGFR inhibitors were designed and synthesized by combination of dithiocarbamic acid esters and 4-anilinoquinazolines. The effect of the synthesized compounds on cell proliferation was evaluated by MTT assay in three human cancer cell lines: MDA-MB-468, SK-BR-3 and HCT-116. Two compounds (11d and 11f) were found more potent against all three cell lines and five compounds (11a, 11d-11g) were found more potent against both MDA-MB-468 and SK-BR-3 than Lapatinib. SAR studies revealed that the substituents on C6 and C7 positions of quinazoline, the amine component of dithiocarbamate moiety and the linker greatly affected the activity. This work provides a promising new strategy for the preparation of potent tyrosine kinase inhibitors.
