573983-56-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 573983-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,3,9,8 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 573983-56:
(8*5)+(7*7)+(6*3)+(5*9)+(4*8)+(3*3)+(2*5)+(1*6)=209
209 % 10 = 9
So 573983-56-9 is a valid CAS Registry Number.

, p. 851 - 862 (2007/10/03)
1-(2-Nitrophenyl)indole-2-carboxylates 5, obtained by the N-arylation of indole-2-carboxylates 4, on catalytic reductive cyclization afford indolo[1,2-a]quinoxalino-6(5H)-ones 6. These compounds on reduction with LAH in ether/THF yielded indolo[1,2-a]quin
