181517-91-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 181517-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,5,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 181517-91:
(8*1)+(7*8)+(6*1)+(5*5)+(4*1)+(3*7)+(2*9)+(1*1)=139
139 % 10 = 9
So 181517-91-9 is a valid CAS Registry Number.

Asymmetric synthesis of β-fluoroaryl-β-amino acids

Davies, Stephen G.,Fletcher, Ai M.,Lv, Linlu,Roberts, Paul M.,Thomson, James E.

, p. 910 - 925 (2012/09/22)

The conjugate addition of lithium (R)-N-benzyl-N-(α-methylbenzyl) amide to a range of β-fluoroaryl-α,β-unsaturated esters gave the corresponding β-amino esters with high diastereoselectivity and in good isolated yields. Sequential treatment of the resulta

, p. 3112 - 3121 (2007/10/03)

Lithium N-benzyl-N-α-methyl-4-methoxybenzylamide may be employed as a homochiral ammonia equivalent for the synthesis of homochiral β-haloaryl β-amino acid derivatives via a strategy involving its conjugate addition to α,β-unsaturated β-haloaryl acceptors and subsequent oxidative deprotection with ceric ammonium nitrate.
