Calculate Digit Verification of CAS Registry Number 121953-46:
(8*1)+(7*2)+(6*1)+(5*9)+(4*5)+(3*3)+(2*4)+(1*6)=116
116 % 10 = 6
So 121953-46-6 is a valid CAS Registry Number.

The Chemistry of N-Substituted Benzotriazoles. Part 20. Mono-N-t-Butylation of Aromatic and Heteroaromatic Amines

Katritzky, Alan R.,Eynde, Jean-Jacques Vanden

, p. 639 - 642 (2007/10/02)

Adducts R1CH(Bt)NHAr, readily available from aldehydes, primary aromatic or heteroaromatic amines, and benzotriazole are converted by H2O2-SeO2 into mixtures of R1CONHAr and HCONR1Ar in proportions which depend rationally on the nature of the R1 group.For R1=But, the formamide HCON(But)Ar is formed in satisfactory yields thus enabling the title reaction to be achieved.
