Check Digit Verification of cas no
The CAS Registry Mumber 2768-89-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,6 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2768-89:
(6*2)+(5*7)+(4*6)+(3*8)+(2*8)+(1*9)=120
120 % 10 = 0
So 2768-89-0 is a valid CAS Registry Number.

Template-Free Solvothermal Synthesis of Flower-Like BiOBr Microspheres in Ethanol Medium for Photocatalytic Applications
Hong, Shaoming,Ren, Huijun,Fang, Yanfeng,Huang, Yingping,Li, Ruiping
, p. 984 - 991 (2018)
Three-dimensionally (3D) BiOBr microflowers were prepared by a simple solvothermal method, employing Bi(NO3)3 · 5H2O and NaBr as starting reagents in ethanol. The structural, light absorption and morphological properties of as-prepared BiOBr microspheres were determined by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV–Vis diffuse reflectance spectroscopy (DRS), etc. The results showed that ethanol acted not only as a solvent but also as a template in 3D BiOBr preparation. The BiOBr microspheres exhibited superior photocatalytic activity compared with 2D BiOBr nanosheets, far exceeding that of TiO2 (Degussa, P25). It was found that both superoxide radical (O2?-) and holes (h+) played a key role in the degradation of RhB by BiOBr microflowers.
