Check Digit Verification of cas no

The CAS Registry Mumber 1190204-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,2,0 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1190204-84:
(9*1)+(8*1)+(7*9)+(6*0)+(5*2)+(4*0)+(3*4)+(2*8)+(1*4)=122
122 % 10 = 2
So 1190204-84-2 is a valid CAS Registry Number.

Microwave-assisted one-pot synthesis of pyrazolo[3,4- b]indoles and new isoxazolo[5,4- b]indoles via copper-catalyzed intramolecular C-N/C-O bond formation

Kumar, Arepalli Sateesh,Rao, P. V. Amulya,Nagarajan, Rajagopal

, p. 3878 - 3886 (2011)

A facile one-pot, two-step synthesis of highly substituted pyrazolo[3,4-b]indoles and isoxazolo[5,4-b]indoles was developed via microwave-assisted, copper-catalyzed intramolecular heterocyclization (involving C-N/C-O bond formation) from 3-acetyl-2-chloroindoles in good to excellent yields.
