Check Digit Verification of cas no

The CAS Registry Mumber 261-42-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,6 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 261-42:
(5*2)+(4*6)+(3*1)+(2*4)+(1*2)=47
47 % 10 = 7
So 261-42-7 is a valid CAS Registry Number.

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

Levy,Agranat

, p. 6157 - 6160 (2007/10/03)

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.

Telluraxanthene

Sadekov, I. D.,Ladatko, A. A.,Minkin, V. I.

, p. 1016 - 1022 (2007/10/02)

Telluraxanthene was obtained by intramolecular electrophilic cyclization of 2-trichlorotelluriodiphenylmethane with subsequent reduction of the intermediately formed 10,10-dichlorotelluraxanthene.The chemical reactions that occur at the tellurium atom and
