Check Digit Verification of cas no
The CAS Registry Mumber 79208-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,0 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 79208-53:
(7*7)+(6*9)+(5*2)+(4*0)+(3*8)+(2*5)+(1*3)=150
150 % 10 = 0
So 79208-53-0 is a valid CAS Registry Number.

Acetylene disulfides RSC2SR, which are furnished with typical thiol protection groups R, were synthesized, fully characterized, and tested with respect to the aimed cleavage of R. While the alkyne RSC2SR with R = C2H4
Versatile route to functionalized 1H-2-benzothiopyrans and 1H-2- naphthothiopyrans by electrophilic cyclization of Bis(arylmethylthio)acetylenes: 2-Benzo- and 2-naphthothiopyrylium salts

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.
