Check Digit Verification of cas no

The CAS Registry Mumber 1620737-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,7,3 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1620737-40:
(9*1)+(8*6)+(7*2)+(6*0)+(5*7)+(4*3)+(3*7)+(2*4)+(1*0)=147
147 % 10 = 7
So 1620737-40-7 is a valid CAS Registry Number.

Ruthenium-catalyzed N-alkylation of amines with alcohols under mild conditions using the borrowing hydrogen methodology

Enyong, Arrey B.,Moasser, Bahram

, p. 7553 - 7563 (2014)

Using a simple amino amide ligand, ruthenium-catalyzed one-pot alkylation of primary and secondary amines with simple alcohols was carried out under a wide range of conditions. Using the alcohol as solvent, alkylation was achieved under mild conditions, even as low as room temperature. Reactions occurred with high conversion and selectivity in many cases. Reactions can also be carried out at high temperatures in organic solvent with high selectivity using stoichiometric amounts of the alcohol.
