82173-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82173-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,7 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82173-72:
(7*8)+(6*2)+(5*1)+(4*7)+(3*3)+(2*7)+(1*2)=126
126 % 10 = 6
So 82173-72-6 is a valid CAS Registry Number.

Regiospecifity in Nucleophilic Displacement of Aromatic Nitro-groups
Benedetti, Fabio,Marshall, Donald R.,Stirling, Charles J. M.,Leng, John L.
, p. 918 - 919 (2007/10/02)
Displacement of nitro-groups by thiolate ions from aromatic polynitro-compounds is highly selective for nitro-groups adjacent to alkyl groups except when the thiolate ion is bulky, the alkyl group is bulky, or both.
