87592-06-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87592-06-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,9 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87592-06:
(7*8)+(6*7)+(5*5)+(4*9)+(3*2)+(2*0)+(1*6)=171
171 % 10 = 1
So 87592-06-1 is a valid CAS Registry Number.

Synthesis of 5H-pyrazolo[5,1-c][1,4]benzodiazepine

Cecchi,Filacchioni

, p. 871 - 873 (1983)

The reaction of 2-nitrobenzyl bromide with dimethyl pyrazole-3,5-dicarboxylate gave dimethyl 1-(2-nitrobenzyl)pyrazole-3,5-dicarboxylate which through a few steps procedure afforded the key intermediate 5,10-dihydro-11-oxopyrazolo[5,1-c][1,4]benzodiazepin
