Check Digit Verification of cas no

The CAS Registry Mumber 956590-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,6,5,9 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 956590-99:
(8*9)+(7*5)+(6*6)+(5*5)+(4*9)+(3*0)+(2*9)+(1*9)=231
231 % 10 = 1
So 956590-99-1 is a valid CAS Registry Number.

Enantioselective ethylation of aldehydes using a regenerable polymer-supported N-picolylvalinol tridentate ligand

Kelsen, Vinciane,Pierrat, Philippe,Gros, Philippe C.

, p. 10693 - 10697 (2007)

A supported pyridine-based tridentate chiral ligand has been prepared and evaluated for enantioselective addition of diethylzinc to aldehydes. The catalyst allowed the preparation of various chiral alcohols with the R configuration in good yields and enan
