210626-00-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 210626-00-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,6,2 and 6 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 210626-00:
(8*2)+(7*1)+(6*0)+(5*6)+(4*2)+(3*6)+(2*0)+(1*0)=79
79 % 10 = 9
So 210626-00-9 is a valid CAS Registry Number.

Versatile route to functionalized 1H-2-benzothiopyrans and 1H-2- naphthothiopyrans by electrophilic cyclization of Bis(arylmethylthio)acetylenes: 2-Benzo- and 2-naphthothiopyrylium salts

Klein,Bergemann,Yehia,Fanghanel

, p. 4626 - 4631 (1998)

Substituted 1H-2-benzothiopyrans find applications as pharmaceutically active compounds or synthons for more complex sulfur heterocycles. However, restricted variability in their synthesis limits the application for research or industrial purposes. To develop a direct and fast route to substituted and functionalized 1H-2-benzothiopyrans, we investigated the ring closure of symmetrical bis(arylmethylthio)acetylenes with iodine monochloride or bromine. This facile reaction yielded 1H-3-halo-4-arylmethylthio-2-benzo- and 2-naphthothiopyrans via postulated vinyl cations in yields of 47-86%. Substituted 2-benzo- and 2-naphthothiopyrylium salts were prepared by hydride abstraction with triphenylcarbenium tetrafluoroborate from the products, further enhancing the synthetic potential of the found cyclization reaction.
