305371-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 305371-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,5,3,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 305371-21:
(8*3)+(7*0)+(6*5)+(5*3)+(4*7)+(3*1)+(2*2)+(1*1)=105
105 % 10 = 5
So 305371-21-5 is a valid CAS Registry Number.

Syntheses and EGFR kinase inhibitory activity of 6-substituted-4-anilino [1,7] and [1,8] naphthyridine-3-carbonitriles

Wissner, Allan,Hamann, Philip R.,Nilakantan, Ramaswamy,Greenberger, Lee M.,Ye, Fei,Rapuano, Timothy A.,Loganzo, Frank

, p. 1411 - 1416 (2007/10/03)

The syntheses and EGFR kinase inhibitory activity of a series of 6-substituted-4-anilino [1,7] and [1,8] naphthyridine-3-carbonitriles are described. Both reversible and irreversible binding inhibitors were prepared. These series were compared with each other and with the corresponding 4-anilinoquinoline-3-carbonitriles. Compounds having a 1,7-naphthyridine core structure can retain high potency while those with a 1,8-naphthyridine core are significantly less active. These results are consistent with molecular modeling observations.
