Check Digit Verification of cas no
The CAS Registry Mumber 31163-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,6 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31163-67:
(7*3)+(6*1)+(5*1)+(4*6)+(3*3)+(2*6)+(1*7)=84
84 % 10 = 4
So 31163-67-4 is a valid CAS Registry Number.

Azoles. Part 32: Nitroindazole derivatives and their electron affinity
Usarewicz,Wrzeciono,Lukaszewski,Gatniejewska,Peisert
, p. 15 - 18 (2007/10/02)
A modified procedure for the synthesis of the dinitroindazoles 5-8 is described. Treatment of the chloronitro- and dinitroindazoles 1-8 with epichlorohydrin afforded the chlorohydroxypropyl- and epoxypropylindazole derivatives 2a-8a, 1b-5b, 7b and 7c. The structure of the compounds is confirmed by the aid of their IR, 1H and 13C NMR spectra. The electron affinity of the nitroindazole derivatives 1-16 is discussed on the basis of their halfwave potentials and in the combination with their eventual radiosensitizing properties.
