64622-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64622-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,2 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 64622-19:
(7*6)+(6*4)+(5*6)+(4*2)+(3*2)+(2*1)+(1*9)=121
121 % 10 = 1
So 64622-19-1 is a valid CAS Registry Number.

μ-Oxo-Dinuclear-Iron(III)-Catalyzed O-Selective Acylation of Aliphatic and Aromatic Amino Alcohols and Transesterification of Tertiary Alcohols

Horikawa, Rikiya,Fujimoto, Chika,Yazaki, Ryo,Ohshima, Takashi

supporting information, p. 12278 - 12281 (2016/08/24)

A highly chemoselective and reactive μ-oxo-dinuclear iron(III) salen catalyst for transesterification was developed. The developed iron complex catalyzed acylation of aliphatic amino alcohols with nearly perfect O-selectivity, even when using activated esters, for which chemoselectivity is more difficult to control. In addition, O-selective transesterification of aromatic amino alcohols was achieved for the first time. The high activity of the iron complex enabled the use of sterically congested tertiary alcohols, including unprecedented tert-butanol.
