Check Digit Verification of cas no
The CAS Registry Mumber 7254-06-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,5 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7254-06:
(6*7)+(5*2)+(4*5)+(3*4)+(2*0)+(1*6)=90
90 % 10 = 0
So 7254-06-0 is a valid CAS Registry Number.

Ring-closure reaction of 2-benzoylbenzenediazonium salts in 1-butyl-3- methylimidazolium ionic liquids

, p. 50 - 59 (2018/02/07)
A ring-closure reaction by thermal dediazoniation of 2-substituted benzenediazonium tetrafluoroborates in imidazolium-based ionic liquids was investigated. Dediazoniation of 2-(4-R-benzoyl)benzenediazonium tetrafluoroborates (R = H, Me, OMe, Cl) in ionic liquid [BMIM][TfO] gave 3-R-9-fluorenones as ring-closure products and 2-(4-R-benzoyl)phenyl trifluoromethanesulfonates as substitution products. Dediazoniation in [BMIM][Tf2N] afforded 3-R-9-fluorenones and R-C6H4-CO-C6H4-OSO(CF3)(NSO2CF3). Yields of the ring-closure products were higher in [BMIM][Tf2N] than in [BMIM][TfO]. 2-Benzylbenzenediazonium and 2-phenoxybenzenediazonium tetrafluoroborates exclusively produced substitution products in both ionic liquids. DFT calculations suggest that electron transfer from the anion to render homolytic process should be induced more readily in [BMIM][Tf2N] than in [BMIM][TfO]. This ability may be responsible for the higher yields of the ring-closure products via homolytic pathway and the smaller yields of the substitution products via heterolytic pathway in [BMIM][Tf2N].
