682804-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 682804-49-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,2,8,0 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 682804-49:
(8*6)+(7*8)+(6*2)+(5*8)+(4*0)+(3*4)+(2*4)+(1*9)=185
185 % 10 = 5
So 682804-49-5 is a valid CAS Registry Number.

, 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
