Check Digit Verification of cas no

The CAS Registry Mumber 1350639-66-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,0,6,3 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1350639-66:
(9*1)+(8*3)+(7*5)+(6*0)+(5*6)+(4*3)+(3*9)+(2*6)+(1*6)=155
155 % 10 = 5
So 1350639-66-5 is a valid CAS Registry Number.

Identification of new 4-N-substituted 6-aryl-7H-pyrrolo[2,3-d]pyrimidine-4- amines as highly potent EGFR-TK inhibitors with Src-family activity

Kaspersen, Svein Jacob,Han, Jin,N?rsett, Kristin G.,Ryds?, Line,Kj?bli, Eli,Bugge, Steffen,Bj?rk?y, Geir,Sundby, Eirik,Hoff, B?rd Helge

, p. 69 - 82 (2014/06/09)

The epidermal growth factor receptor is an important target in molecular cancer therapy. Herein, the enzymatic inhibition potential of a series of chiral and non chiral pyrrolopyrimidine based derivatives have been investigated and optimised. Overall, seven new compounds were identified having enzymatic IC 50 values comparable to or better than the commercial drug Erlotinib. High activity was also confirmed towards the epidermal growth factor receptor L858R and L861Q mutants. Based on calculated druglike properties, eight compounds were further evaluated towards a panel of 52 other kinases revealing interesting Src-family kinase and colony stimulating factor 1 receptor kinase inhibitory activity. Cell proliferation studies with the cell lines A431, C-33A, AU-565, K-562 and genetically engineered Ba/F3-EGFRL858R cells also showed several molecules to be more active than Erlotinib, and thus confirming these pyrrolopyrimidines as attractive drug candidates or lead structures.
