49633-86-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 49633-86-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,6,3 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 49633-86:
(7*4)+(6*9)+(5*6)+(4*3)+(3*3)+(2*8)+(1*6)=155
155 % 10 = 5
So 49633-86-5 is a valid CAS Registry Number.

Novel benzenesulfonamide-bearing pyrazoles and 1,2,4-thiadiazoles as selective carbonic anhydrase inhibitors

Kumar, Rajiv,Kumar, Amit,Ram, Sita,Angeli, Andrea,Bonardi, Alessandro,Nocentini, Alessio,Gratteri, Paola,Supuran, Claudiu T.,Sharma, Pawan K.

, (2021/10/05)

Two series comprising 20 novel benzenesulfonamides bearing thioureido-linked pyrazole 8 and amino-1,2,4-thiadiazole 10 were synthesized and assayed as human carbonic anhydrase (hCA) inhibitors against isoforms I and II as well as the tumor-associated isof

Superacid-promoted synthesis of quinoline derivatives

Klumpp, Douglas A.,Stentzel, Michael R.,Vuong, Hein

supporting information, (2020/01/24)

A series of vinylogous imines have been prepared from anilines and cinnamaldehydes. These substrates react in superacidic media to provide quinolines and related compounds. A mechanism for the conversion is proposed which involves the cyclization of dicationic superelectrophilic intermediates. Aromatization of the quinoline ring is thought to occur by superacid-promoted elimination of benzene.
