124494-11-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124494-11-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,4,9 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 124494-11:
(8*1)+(7*2)+(6*4)+(5*4)+(4*9)+(3*4)+(2*1)+(1*1)=117
117 % 10 = 7
So 124494-11-7 is a valid CAS Registry Number.

Concave reagents. 20. Sterically shielded m-terphenyls as selective agents in general protonations

Luening,Baumgartner,Manthey,Meynhardt

, p. 7922 - 7926 (2007/10/03)

New m-terphenyls with acidic substituants in the 2′-position have been used in general protonations leading to reagent-controlled selectivity enhancements: up to 96:4 for the γ/α-protonation of unsymmetrically substituted allyl anions, up to 97:3 for the protonation of cyclohexyl anions generating preferentially the thermodynamically less stable cis-products. In order to allow a general, reagent-controlled protonation the acidity of the protonating agent should be as low as possible.
