Check Digit Verification of cas no

The CAS Registry Mumber 347339-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,7,3,3 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 347339-21:
(8*3)+(7*4)+(6*7)+(5*3)+(4*3)+(3*9)+(2*2)+(1*1)=153
153 % 10 = 3
So 347339-21-3 is a valid CAS Registry Number.

Manganese-Mediated Reductive Transamidation of Tertiary Amides with Nitroarenes

Cheung, Chi Wai,Ma, Jun-An,Hu, Xile

supporting information, p. 6789 - 6792 (2018/05/29)

Amides are an important class of organic compounds, which have widespread industrial applications. Transamidation of amides is a convenient method to generate new amides from existing ones. Tertiary amides, however, are challenging substrates for transamidation. Here we describe an unconventional approach to the transamidation of tertiary amides using nitroarenes as the nitrogen source under reductive conditions. Manganese metal alone mediates the reactions and no additional catalyst is required. The method exhibits broad scope and high functional group tolerance.
