Check Digit Verification of cas no

The CAS Registry Mumber 1588522-94-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,8,5,2 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1588522-94:
(9*1)+(8*5)+(7*8)+(6*8)+(5*5)+(4*2)+(3*2)+(2*9)+(1*4)=214
214 % 10 = 4
So 1588522-94-4 is a valid CAS Registry Number.

Synthesis and evaluation of 2-anilinopyrimidines bearing 3-aminopropamides as potential epidermal growth factor receptor inhibitors

Han, Chun,Wan, Ledong,Ji, Hongbin,Ding, Ke,Huang, Zhangjian,Lai, Yisheng,Peng, Sixun,Zhang, Yihua

, p. 75 - 83 (2014/04/03)

Novel compounds 12a-i were synthesized and biologically evaluated. Several ones exhibited stronger inhibitory activity than gefitinib against EGFR L858R/T790M and antiproliferative effects on H1975 and HCC827 cells. The 3-aminopropamide in compounds like 12h could be converted to the active acrylamide in the presence of arginine. Importantly, 12h showed improved stability relative to compound 1 whose structure is same to 12h excepting an acrylamide moiety. Interestingly, 12i, a NO donating compound of 12h, showed more potent and selective inhibition than 12h on H1975 cells. Significantly, 12i produced high levels of NO in H1975 cells but not in non-tumorous 16HBE cells, and its inhibition was diminished by NO scavenger. Furthermore, 12i dose-dependently produced inhibitory effects on EGFR downstream signaling in H1975 cells.
