45699-12-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 45699-12-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,5,6,9 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 45699-12:
(7*4)+(6*5)+(5*6)+(4*9)+(3*9)+(2*1)+(1*2)=155
155 % 10 = 5
So 45699-12-5 is a valid CAS Registry Number.

Rhodium(I)-catalyzed one-pot synthesis of dialkyl ketones from methanol and alkenes through directed sp3 C-H bond activation of N-methylamine

Jo, Eun-Ae,Lee, Ji-Hyun,Jun, Chul-Ho

body text, p. 5779 - 5781 (2009/04/13)

The hydroacylation of methanol with alkenes was developed using a catalytic system consisting of Rh(i), 2-amino-4-picoline and benzoic acid; the reaction is speculated to occur by the initial N-methylation of 2-amino-4-picoline with methanol, and the subsequent dehydrogenation of the resulting N-methylamine, followed by double chelation-assisted hydroimination of alkene with the imine to give dialkyl ketones after hydrolysis.

The Chemistry of N-Substituted Benzotriazoles. Part 4. A Novel and Versatile Method for the Mono-N-alkylation of Aromatic and Heteroaromatic Amines

Katritzky, Alan R.,Rachwal, Stanislaw,Rachwal, Bogumila

, p. 805 - 810 (2007/10/02)

Mono-N-alkylation of aromatic and heteroaromatic amines is achieved in high yield by NaBH4 reduction of the adducts formed from benzotriazole, aliphatic aldehydes and the amines.Reaction of the same adducts with Grignard reagents gives N-(secondary alkyl)arylamines.Carboxy groups need no protection and nitro groups are unaffected.Adenine is mono-N-alkylated in high yield.
