28691-27-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28691-27-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,6,9 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28691-27:
(7*2)+(6*8)+(5*6)+(4*9)+(3*1)+(2*2)+(1*7)=142
142 % 10 = 2
So 28691-27-2 is a valid CAS Registry Number.

Tandem catalytic acrylonitrile cross-metathesis and hydrogenation of nitriles with ruthenium catalysts: Direct access to linear α,ω- aminoesters from renewables

Fraternité, Solidarité & complémentarité en Catalyse: Tandem alkene cross-metathesis of acrylonitrile with long-chain alkene and hydrogenation catalysis is performed by using a single ruthenium-alkylidene catalyst precursor. The protocol allows the catalytic transformation of unsaturated fatty acids, derivatives of plant oils, into α,ω-aminoesters. A key step involves the reduction of nitrile-ester intermediates into aminoesters, the precursors of polyamides, with alkene metathesis catalyst residue under mild conditions. Copyright
