Check Digit Verification of cas no
The CAS Registry Mumber 22439-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,4,3 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 22439-61:
(7*2)+(6*2)+(5*4)+(4*3)+(3*9)+(2*6)+(1*1)=98
98 % 10 = 8
So 22439-61-8 is a valid CAS Registry Number.

Photochemistry and photophysics of halogen-substituted dibenzothiophene oxides
Nag, Mrinmoy,Jenks, William S.
, p. 8177 - 8182 (2007/10/03)
Dibenzothiophene-5-oxide (DBTO) cleanly produces dibenzothiophene (DBT) on direct photolysis, but with very low quantum yield. A proposed mechanism involves scission of the S-O bond which is coupled to an intersystem crossing step, thus producing the sulfide and O(3P) via a unimolecular pathway. To test this hypothesis, heavy atom substituted DBTOs were prepared and photolyzed. Iodo-, bromo-, and chloro-substituted DBTOs show higher quantum yields for deoxygenation than does the parent molecule, in the order consistent with an intersystem crossing-related heavy atom effect. 2-Iododibenzothiophene also undergoes photochemical deiodination. Phosphorescence data are consistent with heavy-atom assisted intersystem crossing.
