39887-65-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 39887-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,8,8 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39887-65:
(7*3)+(6*9)+(5*8)+(4*8)+(3*7)+(2*6)+(1*5)=185
185 % 10 = 5
So 39887-65-5 is a valid CAS Registry Number.

Solvent/oxidant-switchable synthesis of multisubstituted quinazolines and benzimidazoles via metal-free selective oxidative annulation of arylamidines

Lin, Jian-Ping,Zhang, Feng-Hua,Long, Ya-Qiu

supporting information, p. 2822 - 2825 (2014/06/23)

A fast and simple divergent synthesis of multisubstituted quinazolines and benzimidazoles was developed from readily available amidines, via iodine(III)-promoted oxidative C(sp3)-C(sp2) and C(sp 2)-N bond formation in nonpolar and polar solvents, respectively. Further selective synthesis of quinazolines in polar solvent was realized by TEMPO-catalyzed sp3C-H/sp2C-H direct coupling of the amidine with K2S2O8 as the oxidant. No metal, base, or other additives were needed.
