81665-11-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81665-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,6 and 5 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81665-11:
(7*8)+(6*1)+(5*6)+(4*6)+(3*5)+(2*1)+(1*1)=134
134 % 10 = 4
So 81665-11-4 is a valid CAS Registry Number.

THERMAL AND PHOTOCHEMICAL REARRANGEMENTS OF 1,4-DITHIIN Sulfoxides
Kobayashi, Keiji,Mutai, Kiyoshi
, p. 5201 - 5204 (2007/10/02)
Thermolysis of 2,5-diphenyl-1,4-dithiin-1-oxide afforded 2-formyl-2,4-diphenyl-1,3-dithiole, which was obtained also in photolysis along with another rearranged product, 2-benzoyl-4-phenyl-1,3-dithiole.
