3408-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3408-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,0 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3408-55:
(6*3)+(5*4)+(4*0)+(3*8)+(2*5)+(1*5)=77
77 % 10 = 7
So 3408-55-7 is a valid CAS Registry Number.

Discovery of chiral catalysts by asymmetric activation for highly enantioselective diethylzinc addition to imines: Using racemic and achiral diimines as effective activators

Liu, Hua,Zhang, Hai-Le,Wang, Shuang-Jun,Mi, Ai-Qiao,Jiang, Yao-Zhong,Gong, Liu-Zhu

, p. 2901 - 2907 (2007/10/03)

A library of chiral zinc complexes formed in situ by the combination of achiral and racemic diimines with 3,3′-di(3,5-ditrifluoromethylphenyl)- BINOL and diethylzinc were evaluated in the asymmetric addition of diethylzinc to N-acylimines. In the presence of 10 mol % of chiral ligand 4 and racemic diimine 5, high enantioselectivities of up to 97% ee and yields of up to 96% were achieved for a wide range of aromatic imines in dichloromethane at -30°C.
