Check Digit Verification of cas no
The CAS Registry Mumber 90361-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,6 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90361-95:
(7*9)+(6*0)+(5*3)+(4*6)+(3*1)+(2*9)+(1*5)=128
128 % 10 = 8
So 90361-95-8 is a valid CAS Registry Number.

SYNTHESIS OF 9H-PYRROLO-1,4-DIAZAINDOL-9-ONE
Laduree, Daniel,Kashef, Hussein El,Robba, Max
, p. 299 - 301 (2007/10/02)
The synthesis of 9H-pyrrolo-1,4-diazaindol-9-one was achieved either by an intramolecular electrophilic substitution of 2-chlorocarbonyl-3-N-pyrrolopyrazine 7 and 2-N-pyrrolidinocarbonyl-3-N-pyrrolopyrazine 8 or by the intramolecular nucleophilic substitution of 2-chloro-3-(2-pyrrolyl)pyrazine 12.
