Check Digit Verification of cas no

The CAS Registry Mumber 1254783-85-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,7,8 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1254783-85:
(9*1)+(8*2)+(7*5)+(6*4)+(5*7)+(4*8)+(3*3)+(2*8)+(1*5)=181
181 % 10 = 1
So 1254783-85-1 is a valid CAS Registry Number.

Discovery of selective irreversible inhibitors for EGFR-T790M

Zhou, Wenjun,Ercan, Dalia,Jaenne, Pasi A.,Gray, Nathanael S.

, p. 638 - 643 (2011/03/18)

Targeting the epidermal growth factor receptor kinase (EGFR) with ATP-competitive kinase inhibitors results in dramatic but short-lived responses in patients with EGFR mutant non small cell lung cancer. A series of novel covalent EGFR kinase inhibitors with selectivity for the clinically relevant T790M 'gatekeeper' resistance mutation relative to wild-type EGFR were discovered by library screening. A representative compound 3i was obtained through a systematic SAR study guided by mutant EGFR-dependent cellular proliferation assays.
