Check Digit Verification of cas no
The CAS Registry Mumber 656233-47-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,6,2,3 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 656233-47:
(8*6)+(7*5)+(6*6)+(5*2)+(4*3)+(3*3)+(2*4)+(1*7)=165
165 % 10 = 5
So 656233-47-5 is a valid CAS Registry Number.

Development of Axially Chiral Cyclo-Biaryldiol Ligands with Adjustable Dihedral Angles

A new type of axially chiral cyclo-[1,1′-biphenyl]-2,2′-diol (CYCNOL) ligands with adjustable dihedral angles have been developed by varying the bridge chain length. Eight-, nine- and ten-membered cyclo-ligands were prepared and evaluated by using two representative examples: enantioselective additions of diethylzinc to aldehydes and organometallic reagents to enones. The results revealed that the fine regulation of dihedral angles through variation of the bridge chain length was effective in the asymmetric synthesis.
