399559-99-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 399559-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,9,5,5 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 399559-99:
(8*3)+(7*9)+(6*9)+(5*5)+(4*5)+(3*9)+(2*9)+(1*9)=240
240 % 10 = 0
So 399559-99-0 is a valid CAS Registry Number.

The synthesis of 1-[(substituted)pyrazol-5-yl]-iminomethyl-2-nitroiminoimidazolidine and its derivatives
Chen,Jin
, p. 1035 - 1038 (2001)
In this article 1-[(substituted)pyrazol-5-yl]iminomethyl-2-nitroimino imidazolidines (II) and their derivatives were synthesized. All the compounds were verified by elemental analysis, 1H NMR and IR. In the reaction of II with halides, two diff
