164913-51-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 164913-51-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,9,1 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 164913-51:
(8*1)+(7*6)+(6*4)+(5*9)+(4*1)+(3*3)+(2*5)+(1*1)=143
143 % 10 = 3
So 164913-51-3 is a valid CAS Registry Number.

Diastereoselective addition of imidazolidin-2-one controlled enolates to activated imines
Roos, Gregory H. P.,Balasubramaniam, Sundari
, p. 755 - 762 (2007/10/03)
Ephedrine-based imidazolidin-2-one chiral auxiliaries afford good syn stereoselectivity in the addition of their derived titanium enolates with an activated imine system. This provides entry into β-amino acid systems.
