Check Digit Verification of cas no

The CAS Registry Mumber 515883-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,5,8,8 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 515883-93:
(8*5)+(7*1)+(6*5)+(5*8)+(4*8)+(3*3)+(2*9)+(1*3)=179
179 % 10 = 9
So 515883-93-9 is a valid CAS Registry Number.

Microwave-mediated synthesis of triazolothiadiazoles as anti-inflammatory, analgesic, and anti-oxidant agents

Sujith,Kalluraya, Balakrishna,Adhikari, Adithya,Vijayanarayana

, p. 543 - 551 (2012)

Efficient approach to the synthesis of a series of triazolothiadiazole analogs of ibuprofen has been carried out using microwave energy. Thus a series of 1,2,4-triazolo[3,4-b]-thiadiazoles 5 were synthesized starting from 4-amino-3-[1-(4-isobutylphenyl)ethyl]-5-mercapto-1,2,4-triazole 3 and different aromatic acids using phosphorous oxychloride as cyclizing agent by microwave and conventional method. Microwave irradiation reduces both time and reaction endeavors along with reduced amount of phosphorous oxychloride. In addition, preliminary results of the biological evaluation of these compounds are also reported and they found to exhibit significant antioxidant, anti-inflammatory, and analgesic activities with reduced ulcerogenicity.
