152190-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152190-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,1,9 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 152190-22:
(8*1)+(7*5)+(6*2)+(5*1)+(4*9)+(3*0)+(2*2)+(1*2)=102
102 % 10 = 2
So 152190-22-2 is a valid CAS Registry Number.

Asymmetric 1,2-Addition of Organolithiums to Aldimines Catalyzed by Chiral Ligand
Inoue, Isao,Shindo, Mitsuru,Koga, Kenji,Tomioka, Kiyoshi
, p. 4429 - 4438 (1994)
An asymmetric 1,2-addition reaction of organolithiums with imines 3, 7 was catalyzed by a 0.05-1.3 equivalent of a chiral amino ether 2 to provide the corresponding optically active amines 4, 8.
