Check Digit Verification of cas no
The CAS Registry Mumber 1785-04-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,8 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1785-04:
(6*1)+(5*7)+(4*8)+(3*5)+(2*0)+(1*4)=92
92 % 10 = 2
So 1785-04-2 is a valid CAS Registry Number.

Aerobic oxidation of 9H-fluorenes to 9-fluorenones using mono-/multilayer graphene-supported alkaline catalyst
Zhang, Xin,Ji, Xuan,Su, Ruifei,Weeks, Brandon L.,Zhang, Zhao,Deng, Songlu
, p. 703 - 711 (2013/07/26)
The synthesis of 9-fluorenone derivatives has been achieved in high yield and with high purity by aerobic oxidation of 9H-fluorenes at room temperature in the presence of a graphene-supported KOH composite that acts as a catalyst in N,N-dimethylformamide. The new protocol involves very simple work-up procedures, and the solvent and the catalyst can be recycled and reused. A scaled-up preparative study employing this method was also conducted and showed its advantages of being both cost-effective and environmentally friendly, and has potential for application in industrial processes.

Improved, highly efficient, and green synthesis of bromofluorenones and nitrofluorenones in water
Zhang, Xin,Han, Jun-Bin,Li, Peng-Fei,Ji, Xuan,Zhang, Zhao
experimental part, p. 3804 - 3815 (2009/12/06)
A series of bromo-, nitro-, and bromonitrofluorenones were synthesized chemo-and regioselectively in 90-98% yield via electrophilic aromatic bromination and nitration under mild conditions using water as the sole solvent. These synthetic methods involve simple workup procedures and use only minimal amounts of organic solvents during the purification of products. The newly developed methods have the advantages of being cost-effective and environmentally friendly and could potentially be used for the large-scale synthesis of fluorenone derivatives.
