Check Digit Verification of cas no

The CAS Registry Mumber 1620843-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,8,4 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1620843-80:
(9*1)+(8*6)+(7*2)+(6*0)+(5*8)+(4*4)+(3*3)+(2*8)+(1*0)=152
152 % 10 = 2
So 1620843-80-2 is a valid CAS Registry Number.

Discovery and synthesis of N2,N4-substitued- cycloalkyl[d]pyrimidine-2,4-diamine analogs: The first examples of small-molecular FGFR-1 activator

Li, Bao-Li,Xiao, Fang,Lu, Wen-Chao,Sun, Yu-Yun,Zhu, Jin,Li, Jian

, p. 989 - 994 (2014/08/18)

A series of novel, cycloalkyl-modified pazopanib analogs 2 and 3 were designed and synthesized. Their kinase modulatory effects on FGFR-1, VEGFR-2, PDGFR-β, and c-KIT were evaluated by the caliper mobility shift assay. Introduction of cycloalkyl into the pyrimidine linker of pazopanib almost abolished the four kinases inhibitory potency of compounds 2 and 3, but surprisingly, resulted in good activation effects on FGFR-1. Compounds 3d and 3g showed double-digit, nanomolar, selective activation effects on FGFR-1, and could be classified as first-generation small molecular activators of FGFR-1 kinase.
