90284-71-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90284-71-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,8 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 90284-71:
(7*9)+(6*0)+(5*2)+(4*8)+(3*4)+(2*7)+(1*1)=132
132 % 10 = 2
So 90284-71-2 is a valid CAS Registry Number.

PARTICIPATION OF PERI-HYDROXYL GROUP IN THE TRIFLUOROACETOLYSIS OF NAPHTHALENESULFONAMIDES
Mazaleyrat, Jean-Paul,Wakselman, Michel
, p. 6071 - 6074 (2007/10/02)
Trifluoroacetolysis of N-alkyl-8-hydroxy-naphthalenesulfonamides generally leads to the corresponding amines and naphthosultones.A model experiment shows that this reaction may be used in a two-step cleavage of sulfonamide protecting groups.
