Meso-1,2-bis(4-methoxyphenyl)-N,N'-dibutylethylendiamin, also known as meso-BPEA, is a chiral ligand used in asymmetric catalysis. It features a central ethylene diamine backbone with two 4-methoxyphenyl groups attached to the 1,2 positions and two butyl groups attached to the nitrogen atoms. This structure endows it with unique steric and electronic properties, making it a valuable component in the design of catalysts for various chemical reactions, particularly those involving the formation of carbon-carbon bonds. Meso-BPEA's ability to create a chiral environment around a metal center allows for the selective synthesis of enantiomerically pure compounds, which is crucial in the pharmaceutical and agrochemical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 4589-09-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,8 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4589-09:
(6*4)+(5*5)+(4*8)+(3*9)+(2*0)+(1*9)=117
117 % 10 = 7
So 4589-09-7 is a valid CAS Registry Number.
