Check Digit Verification of cas no

The CAS Registry Mumber 1240190-21-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,9 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1240190-21:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*9)+(3*0)+(2*2)+(1*1)=99
99 % 10 = 9
So 1240190-21-9 is a valid CAS Registry Number.

Synthesis and preliminary antibacterial evaluation of 2-butyl succinate-based hydroxamate derivatives containing isoxazole rings

Zhang, Datong,Jia, Jiong,Meng, Lijuan,Xu, Weiren,Tang, Lida,Wang, Jianwu

, p. 831 - 842 (2012/01/04)

Two series of novel 2-butyl succinate-based Hydroxamate derivatives containing isoxazole rings were synthesized, characterized and evaluated for antibacterial activity. The synthesized compounds were found to exhibit weak to moderate inhibitory activity against Staphytlococcus aureu and Klebsiellar pneumonia in vitro. All the compounds synthesized were found to be more effective against Klebsiellar pneumonia compared to Staphytlococcus aureu.
