Check Digit Verification of cas no

The CAS Registry Mumber 1017279-02-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,7,2,7 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1017279-02:
(9*1)+(8*0)+(7*1)+(6*7)+(5*2)+(4*7)+(3*9)+(2*0)+(1*2)=125
125 % 10 = 5
So 1017279-02-5 is a valid CAS Registry Number.

Synthesis of substituted 5-bromomethyl-4-nitroimidazoles and use for the preparation of the hypoxia-selective multikinase inhibitor SN29966

Lu, Guo-Liang,Ashoorzadeh, Amir,Anderson, Robert F.,Patterson, Adam V.,Smaill, Jeff B.

, p. 9130 - 9138 (2013/09/24)

5-Bromomethyl-4-nitroimidazoles have utility as bioreductive trigger precursors for the preparation of hypoxia-selective prodrugs. Here we describe an efficient two-step synthesis of 5-(bromomethyl)-1-methyl-4-nitro-1H- imidazole, a preferred precursor, employing an N-bromosuccinimide mediated radical bromination. Use of this precursor to prepare SN29966, a promising hypoxia-selective irreversible pan-ErbB inhibitor is reported along with the preparation of four other prodrug candidates. 5-Bromomethyl-4-nitroimidazole analogues bearing electron-donating and electron-withdrawing substituents at the N-1 and C-2 positions are also described.
