The CAS Registry Mumber 1280219-72-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,1 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1280219-72:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*1)+(3*9)+(2*7)+(1*2)=138
138 % 10 = 8
So 1280219-72-8 is a valid CAS Registry Number.

Synthesis of 3h-quinazolin-4-ones and 4h-3,1-benzoxazin-4-ones via benzylic oxidation and oxidative dehydrogenation using potassium iodide-tert-butyl hydroperoxide

Kumar, R. Arun,Maheswari, C. Uma,Ghantasala, Satheesh,Jyothi,Reddy, K. Rajender

, p. 401 - 410 (2011/04/18)

A simple and elegant method for benzylic activation was demonstrated employing the potassium iodide/tert-butyl hydrogen peroxide catalytic system. This methodology was further extended for the synthesis of biologically important heterocycles namely, 3H-quinazolin-4-ones and 4H-3,1-benzoxazin-4-ones including mecloqualone and etaqualone which are important quinazolinone-based drugs used for the treatment of insomnia in good yields.
