Check Digit Verification of cas no
The CAS Registry Mumber 3920-41-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,2 and 0 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3920-41:
(6*3)+(5*9)+(4*2)+(3*0)+(2*4)+(1*1)=80
80 % 10 = 0
So 3920-41-0 is a valid CAS Registry Number.

A new class of pyrrolo[1,4]benzodiazepine (PBD) analogues featuring a pyrazolo[4,3-e]pyrrolo[1,2-a][1,4]diazepinone ring system has been designed and synthesized. These compounds, 2a-o, are characterized by the substitution of the aromatic A ring, characteristic of the PBDs, with a disubstituted pyrazole ring bearing alkyl and benzyl substituents at N6 or N7 and alkyl or carbomethoxy substituents at C8. Biological evaluation revealed an appreciable in vitro cytotoxic activity for compounds 2a,b,f-i.
