207986-60-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 207986-60-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,9,8 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 207986-60:
(8*2)+(7*0)+(6*7)+(5*9)+(4*8)+(3*6)+(2*6)+(1*0)=165
165 % 10 = 5
So 207986-60-5 is a valid CAS Registry Number.

A new chiral lithium amide based on (S)-2-[1-(3,3- dimethyl)pyrrolidinylmethyl]pyrrolidine-synthesis, NMR studies and use in the enantioselective deprotonation of cyclohexene oxide

Khan, Agha Zul-Qarnain,De Groot, Rimke W.,Arvidsson, Per I.,Davidsson, Oejvind

, p. 1223 - 1229 (1998)

A new chiral lithium amide has been designed starting from (S)-proline. This new chiral lithium amide has been used for asymmetric deprotonation/ring opening of cyclohexene oxide to give (S)-2-cyclohexen-1-ol in 88% yield and 78% enantiomeric excess. NMR studies of the lithium amide and the ligand- substrate complex are also presented.
