Check Digit Verification of cas no
The CAS Registry Mumber 13598-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,9 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13598-56:
(7*1)+(6*3)+(5*5)+(4*9)+(3*8)+(2*5)+(1*6)=126
126 % 10 = 6
So 13598-56-6 is a valid CAS Registry Number.

Preparation of UH3 by the reaction of U with NH3 or with a mixture of H2 and N2
Katsura, Masahiro,Takahashi, Hiroyuki,Hirota, Masayuki,Miyake, Masanobu
, p. 447 - 449 (1994)
To examine how a high nitrogen activity and high hydrogen activity can be obtained by keeping the extent of dissociation of NH3 below its dissociation equilibrium, reactions of U with static NH3 were carried out at 250 °C. The formation of N-rich U2N3+x, and that of UH3 are discussed from a thermodynamic point of view. The experimental results suggest, however, that the formation of UH3 must be ascribed to a much lower activation energy for its formation.
