874141-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 874141-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,1,4 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 874141-27:
(8*8)+(7*7)+(6*4)+(5*1)+(4*4)+(3*1)+(2*2)+(1*7)=172
172 % 10 = 2
So 874141-27-2 is a valid CAS Registry Number.

Asymmetric synthesis of 1,3-aminoketals
Bariau, Annabelle,Canet, Jean-Louis,Chalard, Pierre,Troin, Yves
, p. 3650 - 3660 (2007/10/03)
The asymmetric synthesis of α-chiral 1,3-aminoketals 1, useful chiral building blocks for piperidine preparation, was achieved in seven steps involving highly diastereoselective 1,4-addition of Davies' lithium amide to an α,β-unsaturated ester. Problems o
