Check Digit Verification of cas no

The CAS Registry Mumber 64414-74-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,1 and 4 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 64414-74:
(7*6)+(6*4)+(5*4)+(4*1)+(3*4)+(2*7)+(1*4)=120
120 % 10 = 0
So 64414-74-0 is a valid CAS Registry Number.

Discovery of novel dual inhibitors of receptor tyrosine kinases EGFR and PDGFR-β related to anticancer drug resistance

Fischer, Tim,Najjar, Karim,Totzke, Frank,Sch?chtele, Christoph,Sippl, Wolfgang,Ritter, Christoph,Hilgeroth, Andreas

, p. 1 - 8 (2017/11/14)

With ongoing resistance problems against the marketed EGFR inhibitors having a quinazoline core scaffold there is a need for the development of novel inhibitors having a modified scaffold and, thus, expected lower EGFR resistance problems. An additional problem concerning EGFR inhibitor resistance is an observed heterodimerization of EGFR with PDGFR-β that neutralises the sole inhibitor activity towards EGFR. We developed novel pyrimido[4,5-b]indoles with varied substitution patterns at the 4-anilino residue to evaluate their EGFR and PDGFR-β inhibiting properties. We identified dual inhibitors of both EGFR and PDGFR-β in the nanomolar range which have been initially screened in cancer cell lines to prove a benefit of both EGFR and PDGFR-β inhibition.
