Check Digit Verification of cas no
The CAS Registry Mumber 31594-45-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 31594-45:
(7*3)+(6*1)+(5*5)+(4*9)+(3*4)+(2*4)+(1*5)=113
113 % 10 = 3
So 31594-45-3 is a valid CAS Registry Number.

Substitution reactions of 5-nitropyridine-2-sulfonic acid. A new pathway to 2,5-disubstituted pyridines
Bakke, Jan M.,Sletvold, Ingrid
, p. 2710 - 2715 (2007/10/03)
We have investigated reactions of 5-nitropyridine-2-sulfonic acid and its potassium salt in which substitution of the sulfonate group by oxygen, nitrogen and halogen nucleophiles has been attempted. By this approach, 2-methoxy-(95% yield), 2-ethoxy- (97%), 2-isopropoxy- (65%), 2-amino- (92%), 2- butylamino- (76%), 2-diethylamino- (62%), 2-ethylamino- (32%), 2-benzylamino- (77%), 2-(R-1-phenylethylamino)- (71%) and 2-chloro-5-nitropyridine (87%) have been obtained. No reactions were observed with phenols or anilines. With t-BuOH, 2-hydroxy-5-nitropyridine was formed together with 2-methylpropene.
