Check Digit Verification of cas no

The CAS Registry Mumber 2148-38-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,4 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2148-38:
(6*2)+(5*1)+(4*4)+(3*8)+(2*3)+(1*8)=71
71 % 10 = 1
So 2148-38-1 is a valid CAS Registry Number.

New Tetracyclic Derivatives of Imidazobenzodiazepines and of Imidazothienodiazepines

Gerecke, Max,Kyburz, Emilio,Borer, Rene,Gassner, Walter

, p. 693 - 722 (2007/10/02)

The synthesis of new tetracyclic 1,4-diazepine derivatives is described.In these compounds, an additional five-membered heterocycle is fused on the known tricyclic ring systems imidazobenzodiazepine and imidazothienodiazepine.Many of these new compounds display a very high affinity to the benzodiazepine receptor in mammals.
