Check Digit Verification of cas no
The CAS Registry Mumber 80699-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,9 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 80699-76:
(7*8)+(6*0)+(5*6)+(4*9)+(3*9)+(2*7)+(1*6)=169
169 % 10 = 9
So 80699-76-9 is a valid CAS Registry Number.

Oxygen Atom Transfer from Iodylbenzene to Diphenyl Diselenide - A Convenient Method for Dehydrogenation of Steroidal 3-Ketones
Barton, Derek H. R.,Morzycki, Jacek W.,Motherwell, William B.,Ley, Steven V.
, p. 1044 - 1045 (2007/10/02)
Steroidal 3-ketones are smoothly dehydrogenated in high yield using benzeneseleninic anhydride generated in situ by oxygen atom transfer from iodylbenzene, PhIO2, to catalytic amounts of diphenyl diselenide; use of meta-iodylbenzoic acid in the above cycle has led to the development of an economical and experimentally convenient method avoiding chromatographic separations and with recovery of the m-iodobenzoic acid and the diphenyl diselenide.
