Check Digit Verification of cas no

The CAS Registry Mumber 65273-68-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,7 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65273-68:
(7*6)+(6*5)+(5*2)+(4*7)+(3*3)+(2*6)+(1*8)=139
139 % 10 = 9
So 65273-68-9 is a valid CAS Registry Number.

Well-Defined Phosphine-Free Iron-Catalyzed N-Ethylation and N-Methylation of Amines with Ethanol and Methanol

Lator, Alexis,Gaillard, Sylvain,Poater, Albert,Renaud, Jean-Luc

, p. 5985 - 5990 (2018)

An iron(0) complex bearing a cyclopentadienone ligand catalyzed N-methylation and N-ethylation of aryl and aliphatic amines with methanol or ethanol in mild and basic conditions through a hydrogen autotransfer borrowing process is reported. A broad range of aromatic and aliphatic amines underwent mono- or dimethylation in high yields. DFT calculations suggest molecular hydrogen acts not only as a reducing agent but also as an additive to displace thermodynamic equilibria.
