Check Digit Verification of cas no

The CAS Registry Mumber 1194628-28-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,4,6,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1194628-28:
(9*1)+(8*1)+(7*9)+(6*4)+(5*6)+(4*2)+(3*8)+(2*2)+(1*8)=178
178 % 10 = 8
So 1194628-28-8 is a valid CAS Registry Number.

Copper-catalyzed oxidative arylation of heteroarenes under mild conditions using dioxygen as the sole oxidant

Yang, Fanzhi,Xu, Zhaoqing,Wang, Zhe,Yu, Zhengkun,Wang, Rui

experimental part, p. 6321 - 6325 (2011/08/06)

Dioxy-gently does it! A new copper-catalyzed oxidative cross-coupling reaction between heteroarenes and arylboronic esters has been developed. Uniformly high yields are obtained by using dioxygen as the sole oxidant under mild conditions (see scheme). Copyright

Indium-mediated one-pot synthesis of benzoxazoles or oxazoles from 2-nitrophenols or 1-aryl-2-nitroethanones

Lee, Jung June,Kim, Jihye,Jun, Young Moo,Lee, Byung Min,Kim, Byeong Hyo

experimental part, p. 8821 - 8831 (2009/12/26)

One-pot reduction-triggered heterocyclizations from 2-nitrophenols to benzoxazoles and from 1-aryl-2-nitroethanones to oxazoles were investigated. In the presence of indium/AcOH in benzene at reflux, 2-nitrophenols and R-C(OMe)3 (R=H, Me, Ph) produced excellent yields of corresponding benzoxazoles within an hour. Similarly, 1-aryl-2-nitroethanones and Ph-C(OMe)3 in the presence of indium/AcOH in acetonitrile transformed into the corresponding oxazoles with good yields.
