105443-02-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 105443-02-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,4 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 105443-02:
(8*1)+(7*0)+(6*5)+(5*4)+(4*4)+(3*3)+(2*0)+(1*2)=85
85 % 10 = 5
So 105443-02-5 is a valid CAS Registry Number.

B(C6F5)3-Catalyzed Tandem Friedel-Crafts and C?H/C?O Coupling Reactions of Dialkylanilines

supporting information, p. 3082 - 3086 (2020/09/09)

Tandem Friedel-Crafts (FC) and C?H/C?O coupling reactions catalyzed by tris(pentafluorophenyl) borane (B(C6F5)3) were achieved without using any other additive in the absence of solvent. This process can be used for the reactions between a series of dialkylanilines and vinyl ethers with good isolated yields of bis(4-dialkylaminophenyl) compounds. Based on combined theoretical and experimental studies, the possible reaction mechanism was proposed. B(C6F5)3 can activate the C=C and C?O bond for FC and C?H/C?O coupling reactions respectively. The FC reaction is slow, which is followed by a fast C?H/C?O coupling.
