Check Digit Verification of cas no

The CAS Registry Mumber 1040264-49-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,0,2,6 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1040264-49:
(9*1)+(8*0)+(7*4)+(6*0)+(5*2)+(4*6)+(3*4)+(2*4)+(1*9)=100
100 % 10 = 0
So 1040264-49-0 is a valid CAS Registry Number.

A novel synthesis of EGFR-tyrosine-kinase inhibitors with 4-(indol-3-yl)quinazoline structure

Lueth, Anja,Loewe, Werner

, p. 703 - 708 (2008)

(Chemical Equation Presented) The epidermal growth factor (EGF) family of membrane receptors has been identified as a key element in the complex signaling network that is utilized by various classes of cell-surface receptors. A new synthetic pathway of 4-(indol-3-yl)quinazolines 15 and 16 is described using cross coupling reactions with quinazoline- and indole moieties. The synthesized compound 15 is a new dual and high potent EGFR- and HER-2-tyrosine kinase inhibitor with excellent cytotoxic properties at different cell lines. Furthermore this substance class shows remarkably strong fluorescence.
