408351-97-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 408351-97-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,8,3,5 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 408351-97:
(8*4)+(7*0)+(6*8)+(5*3)+(4*5)+(3*1)+(2*9)+(1*7)=143
143 % 10 = 3
So 408351-97-3 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.
