Purification Methods
Crystallise it from weak aqueous HNO3 (0.5mL/g) by cooling from room temperature. The anhydrous salt can be prepared by dissolving copper metal in a 1:1 mixture of liquid NO2 and ethyl acetate and purified by sublimation [Evans et al. J Chem Soc, Faraday Trans 1 75 1023 1979]. The hexahydrate dehydrates to the trihydrate at 26o, and the anhydrous salt sublimes between 150 and 225o, but melts at 255-256o and is deliquescent.
Check Digit Verification of cas no
The CAS Registry Mumber 10031-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,3 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10031-43:
(7*1)+(6*0)+(5*0)+(4*3)+(3*1)+(2*4)+(1*3)=33
33 % 10 = 3
So 10031-43-3 is a valid CAS Registry Number.
