1346601-52-2 Usage
Uses
Erlotinib (E625000) derivative as internal standard for HPLC.
Biological Activity
4-methyl erlotinib is an analog of erlotinib by the addition of a methyl group at the four position of the phenyl group. erlotinib is a tyrosine kinase inhibitor which acts on the epidermal growth factor receptor (egfr) [1].the epidermal growth factor receptor (egfr) autocrine pathway has been important for cancer development and progression, including cell proliferation, apoptosis, angiogenesis, and metastatic spread [2].erlotinib inhibits egfr-associated kinase activity by binding to the egf-activated receptor, with the phenyl group at one end sequestered in a hydrophobic pocket of the kinase domain and the ether linkages at the opposite end projecting into solvent [1].erlotinib can prolong survival in patients with non–small-cell lung cancer after first-line or second-line chemotherapy [3].

Check Digit Verification of cas no
The CAS Registry Mumber 1346601-52-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,6,6,0 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1346601-52:
(9*1)+(8*3)+(7*4)+(6*6)+(5*6)+(4*0)+(3*1)+(2*5)+(1*2)=142
142 % 10 = 2
So 1346601-52-2 is a valid CAS Registry Number.
