Check Digit Verification of cas no

The CAS Registry Mumber 17987-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,8 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 17987-78:
(7*1)+(6*7)+(5*9)+(4*8)+(3*7)+(2*7)+(1*8)=169
169 % 10 = 9
So 17987-78-9 is a valid CAS Registry Number.

Design, synthesis, and biological evaluation studies of novel quinazolinone derivatives as anticonvulsant agents

Zayed, Mohamed F.,Ahmed, Hany E. A.,Omar, Abdel-Sattar M.,Abdelrahim, Adel S.,El-Adl, Khaled

, p. 5823 - 5831 (2013/11/06)

In view of their expected anticonvulsant activity, some novel derivatives of 6,8-diiodo-2-methyl-3-substituted-quinazolin-4(3H)-ones (4-14) were synthesized, evaluated for their anticonvulsant activity by the maximal electroshock-induced seizure and subcutaneous pentylenetetrazole tests. The neurotoxicity was assessed using rotorod test. All the tested compounds showed considerable anticonvulsant activity in at least one of the anticonvulsant tests. Compounds 5, 6, and 8 proved to be the most potent compounds of this series with relatively low neurotoxicity and low toxicity in the median lethal dose test when compared with the reference drugs. The obtained results showed that the most potent compounds could be useful as a template for future design, optimization, and investigation to produce more active analogs.
