Check Digit Verification of cas no

The CAS Registry Mumber 228555-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,5,5 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 228555-28:
(8*2)+(7*2)+(6*8)+(5*5)+(4*5)+(3*5)+(2*2)+(1*8)=150
150 % 10 = 0
So 228555-28-0 is a valid CAS Registry Number.

Enantioselective addition of diethylzinc to aldehydes with novel chiral C2-symmetric dimeric ligands

Okaniwa, Masanori,Yanada, Reiko,Ibuka, Toshiro

, p. 1047 - 1050 (2007/10/03)

Novel (S)-valinol-based chiral C2-2,2'-ethylenediiminodiethanol derivatives 4a and 4b have been synthesized and used as chiral catalysts in the enantioselective addition of diethylzinc to aldehydes. (R)-1- Phenylpropanol has been obtained in up
