Check Digit Verification of cas no
The CAS Registry Mumber 103708-19-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,7,0 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103708-19:
(8*1)+(7*0)+(6*3)+(5*7)+(4*0)+(3*8)+(2*1)+(1*9)=96
96 % 10 = 6
So 103708-19-6 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.
