Check Digit Verification of cas no
The CAS Registry Mumber 27090-16-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,0,9 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 27090-16:
(7*2)+(6*7)+(5*0)+(4*9)+(3*0)+(2*1)+(1*6)=100
100 % 10 = 0
So 27090-16-0 is a valid CAS Registry Number.

Zinc-mediated reductive dimerizations of telluroxanthone and selenoxanthone. Tellurium-selenium selectivity
Levy,Agranat

Reductive dimerizations of 9H-selenoxanthen-9-one (3) and 9H-telluroxanthen-9-one (4) (1:1) with zinc in boiling AcOH and HCl for 1 hour gave the bistricyclic ethanes 9,9'-bi(9H-selenoxanthene (10), 9,9'-bi(9H-telluroxanthene) (11) and 9-(9'H-telluroxanthen-9'-yl)-9H-selenoxanthene (12) in the ratios 21 (10):35 (11):44 (12) (in addition to 9H-selenoxanthene (13) and 9H-telluroxanthene (14)) Analogous reactions of 4 and 9H-thioxanthen-9-one (9) (1:1) and 3 and 9 (1:1) gave the corresponding bistricyclic ethanes. The reactions were chalcogen selective with a preference towards the tellurium-bridged bistricyclic ethanes. (C) 2000 Elsevier Science Ltd.
