Check Digit Verification of cas no

The CAS Registry Mumber 1289163-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,1,6 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1289163-67:
(9*1)+(8*2)+(7*8)+(6*9)+(5*1)+(4*6)+(3*3)+(2*6)+(1*7)=192
192 % 10 = 2
So 1289163-67-2 is a valid CAS Registry Number.

DABCO-catalyzed oxidation of deoxybenzoins to benzils with air and one-pot synthesis of quinoxalines

Qi, Chaorong,Jiang, Huanfeng,Huang, Liangbin,Chen, Zhengwang,Chen, Huoji

experimental part, p. 387 - 396 (2011/04/15)

Aerobic oxidation of deoxybenzoins could be efficiently catalyzed by 1,4-diazabicyclo[2.2.2]octane (DABCO) with air as the sole oxidant to give the corresponding benzils in excellent yields. The effects of reaction conditions, such as different bases, temperature, time and solvent, on the yield of the product were investigated. Moreover, the process has been successfully extended to a one-pot synthesis of quinoxalines from benzyl ketones and aromatic 1,2-diamines. Georg Thieme Verlag Stuttgart New York.
