Check Digit Verification of cas no
The CAS Registry Mumber 2983-05-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,8 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2983-05:
(6*2)+(5*9)+(4*8)+(3*3)+(2*0)+(1*5)=103
103 % 10 = 3
So 2983-05-3 is a valid CAS Registry Number.

Chemistry of Dioxiranes. 21. Thermal Reactions of Dioxiranes
Singh, Megh,Murray, Robert W.
, p. 4263 - 4270 (2007/10/02)
Thermolysis of dioxiranes in solutions of their parent ketones or in mixtures of the parent ketone and a foreign ketone leads to the formation of esters.The results are explained by postulating a free-radical mechanism involving H atom abstraction from the ketones.The resulting radicals are converted to the observed esters by reaction with acyloxy radicals derived from homolysis of the dioxiranes.Autodecomposition of dimethyldioxirane in acetone solution at room temperature gives methyl acetate at a very slow rate.When catalyzed by BF3 etherate the same decomposition proceeds much more rapidly and is accompanied by acetol formation.
