The precipitate obtained by adding 10mL of conc HCl to the cooled filtrate is collected, washed with 95% EtOH until the washings are colourless, and is dried under vacuum over CaCl2. It is stored in a dark-coloured bottle, in the cold [Chanley et al. J Am Chem Soc 74 4347 1952]. [Beilstein 14 IV 2825.]
Check Digit Verification of cas no
The CAS Registry Mumber 116-63-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 116-63:
(5*1)+(4*1)+(3*6)+(2*6)+(1*3)=42
42 % 10 = 2
So 116-63-2 is a valid CAS Registry Number.

Aromatic C-nitrosation by a copper(ii)-nitrosyl complex
Rout, Kanhu Charan,Mondal, Biplab
, p. 1829 - 1835 (2015)
Copper(ii) complex of 4-amino-3-hydroxy-1-sulphonic acid was synthesized and characterized. Upon addition of nitric oxide, the copper(ii) center of the complex in methanol was found to undergo reduction through an unstable copper(ii)-nitrosyl intermediate. The formation of the intermediate was confirmed by UV-visible and FT-IR spectroscopy. The reduction of the copper(ii) center was accompanied with a simultaneous C-nitrosation of the aromatic ring of the ligand. The C-nitrosation product was isolated and characterized by various spectroscopic analyses. This journal is
