Check Digit Verification of cas no
The CAS Registry Mumber 29924-57-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,2 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 29924-57:
(7*2)+(6*9)+(5*9)+(4*2)+(3*4)+(2*5)+(1*7)=150
150 % 10 = 0
So 29924-57-0 is a valid CAS Registry Number.

Reissert Compound Studies. XXXVI. Observations on 1,7-, 4,6-, 4,7- and 1,10-Phenanthrolines
Bhattacharjee, D.,Popp, F. D.
, p. 1207 - 1210 (2007/10/02)
Reissert compounds have been prepared from 1,7-, 4,6-, and 4,7-phenanthrolines.In the case of 4,7-phenanthroline, both mono- and di-Reissert compounds have been prepared.A number of Reissert analogs have also been prepared in this series. 1,10-Phenanthroline fails to give a Reissert compound.
