Check Digit Verification of cas no

The CAS Registry Mumber 44520-52-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,4,5,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 44520-52:
(7*4)+(6*4)+(5*5)+(4*2)+(3*0)+(2*5)+(1*2)=97
97 % 10 = 7
So 44520-52-7 is a valid CAS Registry Number.

One-pot reductive amination of carboxylic acids: a sustainable method for primary amine synthesis

Coeck, Robin,De Vos, Dirk E.

, p. 5105 - 5114 (2020)

The reductive amination of carboxylic acids is a very green, efficient and sustainable method for the production of (bio-based) amines. However, with current technology, this reaction requires two to three reaction steps. Here, we report the first (heterogeneous) catalytic system for the one-pot reductive amination of carboxylic acids to amines, with solely H2 and NH3 as the reactants. This reaction can be performed with relatively cheap ruthenium-tungsten bimetallic catalysts in the green and benign solvent cyclopentyl methyl ether (CPME). Selectivities of up to 99% for the primary amine could be achieved at high conversions. Additionally, the catalyst is recyclable and tolerant for common impurities such as water and cations (e.g. sodium carboxylate).
