108683-66-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 108683-66-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,6,8 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 108683-66:
(8*1)+(7*0)+(6*8)+(5*6)+(4*8)+(3*3)+(2*6)+(1*6)=145
145 % 10 = 5
So 108683-66-5 is a valid CAS Registry Number.

Asymmetric protonation of ketone enolates using chiral β- hydroxyethers: Acidity-tuned enantioselectivity

Kim, B. Moon,Kim, Hyunwoo,Kim, Woosung,Im, Keun Young,Park, Jin Kyoon

, p. 5104 - 5107 (2007/10/03)

New chiral hydroxyethers 1a-f were prepared for asymmetric protonation of achiral enolates prepared from prochiral ketones. The enantioselectivity of protonation was highly dependent upon the acidity of the chiral alcohols, the highest enantioselectivity
