Check Digit Verification of cas no

The CAS Registry Mumber 735-28-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,3 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 735-28:
(5*7)+(4*3)+(3*5)+(2*2)+(1*8)=74
74 % 10 = 4
So 735-28-4 is a valid CAS Registry Number.

Copper-catalyzed radical methylation/C-H amination/oxidation cascade for the synthesis of quinazolinones

Bao, Yajie,Yan, Yizhe,Xu, Kun,Su, Jihu,Zha, Zhenggen,Wang, Zhiyong

, p. 4736 - 4742 (2015/05/13)

A copper-catalyzed radical methylation/sp3 C-H amination/oxidation reaction for the facile synthesis of quinazolinone was developed. In this cascade reaction, dicumyl peroxide acts not only as a useful oxidant but also as an efficient methyl source. Notably, a methyl radical, generated from peroxide, was confirmed by electron paramagnetic resonance for the first time.

Stannous chloride in alcohol: A one-pot conversion of 2-Nitro-N- arylbenzamides to 2,3-Dihydro-1H-quinazoline-4-ones

Yoo, Choong Leol,Fettinger, James C.,Kurth, Mark J.

, p. 6941 - 6943 (2007/10/03)

A novel one-step synthesis of 2,3-dihydro-1H-quinazolin-4-ones from 2-nitrobenzamides is reported. These reactions are mediated by stannous chloride in 0.02 M methanolic or ethanolic HCl solution and proceed in good yields.
