Check Digit Verification of cas no

The CAS Registry Mumber 95320-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,3,2 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 95320-95:
(7*9)+(6*5)+(5*3)+(4*2)+(3*0)+(2*9)+(1*5)=139
139 % 10 = 9
So 95320-95-9 is a valid CAS Registry Number.

Ring closure reactions of 3-arylhydrazonoalkyl-quinolin-2-ones to 1-aryl-pyrazolo[4,3-c]quinolin-2-ones

Stadlbauer, Wolfgang,Hojas, Gerhard

, p. 681 - 690 (2007/10/03)

4-Hydroxy-3-arylhydrazonoalkyl-2-quinolones 6 or reactive derivatives such as 3-arylhydrazonoalkyl-4-tosyloxy-2-quinolones 7 or 4-chloro-3- arylhydrazonoalkyl-2-quinolones 14, which are obtained via 3-acyl-4- hydroxyquinolones 4, 10 or 3-phenylaminomethylene-quinoline-2,4-diones 12, cyclize in excellent yields to 1-aryl-pyrazolo[4,3-c]quinolin-4-ones (11). The cyclization conditions were investigated by differential scanning calorimetry (DSC).
