Check Digit Verification of cas no
The CAS Registry Mumber 58041-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,0,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 58041-19:
(7*5)+(6*8)+(5*0)+(4*4)+(3*1)+(2*1)+(1*9)=113
113 % 10 = 3
So 58041-19-3 is a valid CAS Registry Number.

On treatment with tellurium tetrachloride in dichloromethane at room temperature, 1,3-dithiolanes and 1,3-oxathiolanes undergo smooth ring expansion to give dihydro-1,4-dithiin and dihydro-1,4-oxathiin derivatives respectively in good to moderate yields.
EFFECTS OF HETEROATOM SUBSTITUENTS ON THE PROPERTIES OF 1,2-DIOXETANES
Handley, Richard S.,Stern, Alan J.,Schaap, A. Paul
, p. 3183 - 3186 (2007/10/02)
Nitrogen and sulfur-substituted dioxetanes exhibit dramatically lower activation energies for decomposition compared to the corresponding oxygen-bearing dioxetane.A mechanism involving intramolecular electron-transfer processes is proposed for the cleavage of these unstable dioxetanes.
