Check Digit Verification of cas no

The CAS Registry Mumber 457089-18-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,0,8 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 457089-18:
(8*4)+(7*5)+(6*7)+(5*0)+(4*8)+(3*9)+(2*1)+(1*8)=178
178 % 10 = 8
So 457089-18-8 is a valid CAS Registry Number.

Synthesis of novel triazoles, tetrazine, thiadiazoles and their biological activities

Al-Omair, Mohammed A.,Sayed, Abdelwahed R.,Youssef, Magdy M.

, p. 2591 - 2610 (2015)

An expedient synthesis of novel triazoles, tetrazine and thiadiazoles, using conveniently accessible and commercially available starting materials has been achieved. The synthesized compounds were characterized by spectroscopic and elemental analyses, and screened for their antibacterial activities against four different strains, namely E. coli, P. aeruginosa, S. aureus and B. megaterium. In particular, the compounds 5, 24 and 26h exhibited excellent antibacterial activities compared to the reference antibiotic. To get further insight about their behavior, these compounds were tested for their antioxidant activities via SOD-like activity, DPPH free radical scavenging activity, ABST and NO, which showed promising results. Furthermore, these compounds effectively promoted the cleavage of genomic DNA as well, in the absence of any external additives.
