1421373-32-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1421373-32-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,7 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1421373-32:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*7)+(3*3)+(2*3)+(1*2)=121
121 % 10 = 1
So 1421373-32-1 is a valid CAS Registry Number.

-

, (2020/03/19)

The invention relates to a compound containing a conjugated allene amide structure and a preparation method, a medicine composition and application thereof, in particular to a compound containing a conjugated allene amide structure shown in a formula (I), and a preparation method, a medicine composition and application thereof in preparation of an EGFR (epidermal growth factor receptor) inhibitoror a medicine for preventing and/or treating EGFR-related diseases, especially cancers. (The formula (I) is shown in the description.).

EGFR INHIBITOR, AND PREPARATION AND APPLICATION THEREOF

-

, (2017/09/02)

A 4-substituted-2-(N-(5-substituted allyl amide)phenyl)amino)pyrimidine derivative as represented by formula (I), and a preparation and application thereof as an EGFR inhibitor. The compound has activity of inhibiting the L858R EGFR mutant, the T790M EGFR mutant and the exon 19 deletion activating mutant, may be used to treat diseases mediated alone or in part by EGFR mutant activity, and has a wide application in drugs preventing and treating cancers, particularly non-small cell lung cancer.

2 - (2, 4, 5 - SUBSTITUTED -ANILINO) PYRIMIDINE DERIVATIVES AS EGFR MODULATORS USEFUL FOR TREATING CANCER

-

, (2013/03/26)

The present invention relates to certain 2-(2,4,5-substituted-anilino) pyrimidine compounds and pharmaceutically acceptable salts thereof which may be useful in the treatment or prevention of a disease or medical condition mediated through certain mutated forms of epidermal growth factor receptor (for example the L858R activating mutant, the Exonl9 deletion activating mutant and the T790M resistance mutant). Such compounds and salts thereof may be useful in the treatment or prevention of a number of different cancers. The invention also relates to pharmaceutical compositions comprising said compounds and salts thereof, especially useful polymorphic forms of these compounds and salts, intermediates useful in the manufacture of said compounds and to methods of treatment of diseases mediated by various different forms of EGFR using said compounds and salts thereof.
