Check Digit Verification of cas no

The CAS Registry Mumber 449186-61-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,9,1,8 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 449186-61:
(8*4)+(7*4)+(6*9)+(5*1)+(4*8)+(3*6)+(2*6)+(1*1)=182
182 % 10 = 2
So 449186-61-2 is a valid CAS Registry Number.

Antitumour polycyclic acridines. Part 9. Synthesis of 7H-pyrido[4,3,2-kl]acridines with basic side chains

Ellis, Michael J.,Stevens, Malcolm F.G.

, p. 3174 - 3179 (2001)

[3 + 2] Cycloaddition of 3-(dialkylamino)-1-triphenylphosphoranylidenepropan-2-ones and 9-azidoacridine affords 9-[5-(dialkylaminomethyl)-1H-1,2,3-triazol-1-yl]acridines. Graebe-Ullmann thermolysis of the triazoles has been guided by differential scanning calorimetry to predict the optimum temperature for nitrogen extrusion. Boiling diphenyl ether (bp 259°C) is a suitable solvent to convert the triazolylacridines to 2-(dialkylaminomethyl)-7H-pyrido[4,3,2-kl]acridines.
