Check Digit Verification of cas no
The CAS Registry Mumber 5416-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,1 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5416-22:
(6*5)+(5*4)+(4*1)+(3*6)+(2*2)+(1*2)=78
78 % 10 = 8
So 5416-22-8 is a valid CAS Registry Number.

Halogenating and nitrating activity of reagents based on sodium nitrate and alkali metal halides in acetic acid
Filimonov,Kulmanakova,Yusubov,Perederina,Chi, Ki-Whan,Poleshchuk
, p. 917 - 923 (2004)
Alkali metal halides NaF, KCl, and KBr sharply enhance the nitrating activity of sodium nitrate in acetic acid with respect to 9-methylcarbazole. In the presence of KI and KBr, both nitration and halogenation of the substrate occurs, while KCl and NaF promote only the nitration process. The results may be interpreted in terms of formation of the corresponding nitryl halides XNO2 (X = F, Cl, Br, I) whose structure and reactivity were examined in the framework of the density functional theory (DFT B3LYP/3-21G*).
