Check Digit Verification of cas no

The CAS Registry Mumber 1334287-93-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,2,8 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1334287-93:
(9*1)+(8*3)+(7*3)+(6*4)+(5*2)+(4*8)+(3*7)+(2*9)+(1*3)=162
162 % 10 = 2
So 1334287-93-2 is a valid CAS Registry Number.

Catalytic Asymmetric Reduction of α-Trifluoromethylated Imines with Catecholborane by BINOL-Derived Boro-phosphates

He, Hualing,Tang, Xiaoxue,Cao, Yang,Antilla, Jon C.

, p. 4336 - 4345 (2021/03/01)

A catalytic enantioselective reduction of α-trifluoromethylated imines by a BINOL-derived boro-phosphate employing catecholborane as hydride source has been developed. This method provides an efficient route to prepare synthetically useful chiral α-triflu

Palladium(II)-catalyzed enantioselective synthesis of α- (trifluoromethyl)arylmethylamines

Johnson, Thomas,Lautens, Mark

, p. 4043 - 4045 (2013/09/12)

Trifluoromethylacetaldimines, generated in situ from the corresponding N,O-acetals, undergo 1,2-addition of arylboroxines under palladium(II) catalysis to generate a variety of α-(trifluoromethyl)arylmethylamines with good to high enantioselectivity (up to 97% ee). The pyridine-oxazolidine (PyOX) class of ligands was found to be particularly suitable for this transformation, which proceeds without exclusion of ambient air and moisture.

Chiral phosphoric acid catalyzed transfer hydrogenation: Facile synthetic access to highly optically active trifluoromethylated amines

Henseler, Alexander,Kato, Masanori,Mori, Keiji,Akiyama, Takahiko

supporting information; experimental part, p. 8180 - 8183 (2011/10/09)

Amines to an end: Highly optically active α-CF3- functionalized amines can be obtained using metal-free reaction conditions. The method involves the transfer hydrogenation of CF3-substituted ketimines catalyzed by 1 and reductive ami
