83520-06-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83520-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83520-06:
(7*8)+(6*3)+(5*5)+(4*2)+(3*0)+(2*0)+(1*6)=113
113 % 10 = 3
So 83520-06-3 is a valid CAS Registry Number.

Amino acid amide derivatives of 2-[3-(aminomethyl)-4H-1,2,4-triazol-4-yl]benzophenones, a novel class of annelated peptidoaminobenzophenones

Hirai,Fujishita,Ishiba,Sugimoto,Matsutani,Tsukinoki,Hirose

, p. 1466 - 1473 (2007/10/02)

A series of the title compounds was prepared via condensation of the 3-(aminomethyl)triazolylbenzophenone with N-protected amino acids, followed by deprotection, amination of the 3-[(chloroacetamido)methyl]triazolylbenzophenone, or reduction of the relevant azide derivative. Some of the title compounds were also derived directly from the quinazolines by acid-induced rearrangement, followed by deprotection. These new amino acid amide derivatives of the triazolylbenzophenones were evaluated for central nervous system (CNS) activity. Members of this class of compounds exhibited a high level of CNS activities. For example, 2',5-dichloro-2-[3-[(glycylamino)methyl]-5-methyl-4H-1,2,4-triazol-4-yl ]benzophenone was as active as triazolam, with an ED50 of 0.58 mg/kg (mice, po), against antifighting activity in the foot shock-induced fighting test. Other triazolylbenzophenone derivatives showed similar pharmacological activities.
