Calculate Digit Verification of CAS Registry Number 51439-03:
(7*5)+(6*1)+(5*4)+(4*3)+(3*9)+(2*0)+(1*3)=103
103 % 10 = 3
So 51439-03-3 is a valid CAS Registry Number.

Ardiansah, Bayu,Kakiuchi, Kiyomi,Morimoto, Tsumoru,Tanimoto, Hiroki,Tomohiro, Takenori

, p. 8738 - 8741 (2021/09/08)

Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C-H and C-C bonds was accessible to the one-pot substitution reaction.
