Calculate Digit Verification of CAS Registry Number 18552-44:
(7*1)+(6*8)+(5*5)+(4*5)+(3*2)+(2*4)+(1*4)=118
118 % 10 = 8
So 18552-44-8 is a valid CAS Registry Number.

Conversion of furfural to tetrahydrofuran-derived secondary amines under mild conditions

Jiang, Shi,Muller, Eric,Jer?me, Fran?ois,Pera-Titus, Marc,De Oliveira Vigier, Karine

supporting information, p. 1832 - 1836 (2020/04/09)

The production of amino-containing compounds from biomass is an important goal of research programs. Starting from carbohydrate-based furfural, a simple and highly efficient system was developed for producing a library of secondary and tertiary tetrahydrofurfurylamines under mild conditions (25 °C/1 bar H2) with excellent yields (>90%). Commercially available Pd/Al2O3 proved to be a suitable catalyst and exhibited outstanding performance.
