Check Digit Verification of cas no

The CAS Registry Mumber 202808-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,8,0 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 202808-17:
(8*2)+(7*0)+(6*2)+(5*8)+(4*0)+(3*8)+(2*1)+(1*7)=101
101 % 10 = 1
So 202808-17-1 is a valid CAS Registry Number.

Cyclic hydrazides. 2. synthesis of substituted 4-hydroxy-1-oxo-1,2-dihydropyridazino[4,5-b]quinoline 5-oxides

Rozhkov,Piskunova,Gol'd,Kalvin'sh

, p. 222 - 231 (1998)

Reaction of N-oxides of dimethyl quinoline-2,3-dicarboxylates with hydrazine and subsequent oxidation with peracetic acid has given quinoline-2,3-dicarboxylic acid hydrazide 5-oxides, from which water soluble-quaternary ammonium salts can be prepared. 199
