Check Digit Verification of cas no

The CAS Registry Mumber 65022-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,2 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 65022-20:
(7*6)+(6*5)+(5*0)+(4*2)+(3*2)+(2*2)+(1*0)=90
90 % 10 = 0
So 65022-20-0 is a valid CAS Registry Number.

Peptidoaminobenzophenones, a novel class of ring-opened derivatives of 1,4-benzodiazepines

Hirai,Ishiba,Sugimoto,Sasakura,Fujishita,Toyoda,Tsukinoki,Joyama,Hatakeyama,Hirose

, p. 764 - 773 (2007/10/02)

A series of novel peptidoaminobenzophenones has been prepared via several routes and was evaluated for CNS activity. The structure-activity relationships in the series are discussed. In general, dipeptido-N-methylaminobenzophenones showed higher activities than the corresponding NH derivatives. Some compounds had very high activities in antipentylenetetrazole and antifighting tests in mice when orally administered. Very weak toxicity was also found in these compounds. Water solubility of the peptidoaminobenzophenones and their salts were tested. Possible in vivo conversion of peptidoaminobenzophenone by enzymatic cleavage of the terminal amino acid, followed by chemical cyclization to 1,4-benzodiazepine, is also discussed. Such novel open-ring derivatives of 1,4-benzodiazepine may serve as useful CNS agents.
