98516-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98516-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,1 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98516-25:
(7*9)+(6*8)+(5*5)+(4*1)+(3*6)+(2*2)+(1*5)=167
167 % 10 = 7
So 98516-25-7 is a valid CAS Registry Number.

SYNTHESIS OF BUNTE SALTS FROM 1,2-BENZISOTHIAZOL-3-ONES AND VICE VERSA
Tyrrell, A. W. R.
, p. 1753 - 1756 (2007/10/02)
1,2-Benzisothiazol-3-ones undergo ring-opening when treated with sodium hydrogen sulphite solution, giving Bunte salts, reconversion of which to benzisothiazol-3-ones can be effected with dilute alkali.
