181712-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181712-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,7,1 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 181712-72:
(8*1)+(7*8)+(6*1)+(5*7)+(4*1)+(3*2)+(2*7)+(1*2)=131
131 % 10 = 1
So 181712-72-1 is a valid CAS Registry Number.

New functionalized α-carbolinones especially the 4-hydroxy-3-nitro-1H,9H-pyrido[2,3-b]indol-2-one were synthesized in a good yield, three-step reaction. A complete 13C, 15N nmr study of this carbolinone and precursors is presented.
