Check Digit Verification of cas no
The CAS Registry Mumber 19955-28-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,5 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19955-28:
(7*1)+(6*9)+(5*9)+(4*5)+(3*5)+(2*2)+(1*8)=153
153 % 10 = 3
So 19955-28-3 is a valid CAS Registry Number.

Sulfur-containing heterocycles 14.* new synthesis of cyclic anhydrides of 3-sulfinocarboxylic acids
Vasil'eva,Shchetnikov,Osipov
, (2009)
3-Chlorosulfinylalkanoyl chlorides undergo cyclization into the corresponding five-membered mixed anhydrides (1,2-oxathiolan-5-one 2-oxides) under the action of sodium or mercury acetates. 2-Chlorosulfinylbenzoyl chloride gives 3H-2,1-benzoxathiol-3-one 1
