74738-21-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74738-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74738-21:
(7*7)+(6*4)+(5*7)+(4*3)+(3*8)+(2*2)+(1*1)=149
149 % 10 = 9
So 74738-21-9 is a valid CAS Registry Number.

Scope of the organocatalysed asymmetric reductive amination of ketones with trichlorosilane

Gautier, Franois-Moana,Jones, Simon,Li, Xianfu,Martin, Stephen J.

experimental part, p. 7860 - 7868 (2011/12/02)

A highly active organocatalyst has been shown to affect the asymmetric reductive amination of ketones producing both aromatic and aliphatic amines. At 1 mol% catalyst loading, a series of structurally diverse chiral amines were quickly and economically prepared with good enantioselectivity and generally useful yield. The efficient synthesis of the calcimimetic (+)-NPS R-568 (67%, 89% ee) demonstrated the synthetic applicability of this methodology.

STEREOCHEMISTRY OF THE DEALKOXYCARBONYLATION OF METHYL Α-CYANOCINNAMATE AND OF THE DECARBOXYLATION OF THE CORRESPONDING CYANOACID: A FACILE STEREOSELECTIVE ROUTE TO Z-CINNAMONITRILE

Babler, James H.,Spina, Kenneth P.

, p. 3835 - 3838 (2007/10/02)

Decarboxylation of E-3-phenyl-2-cyanopropenoic acid (1) in dimethyl sulfoxide containing sodium bicarbonate, lithium chloride, and water in molar excess afforded, with high stereospecifity, Z-cinnamonitrile (6).The dealkoxycarbonylation of the corresponding methyl ester (2) under similar reaction conditions was much less selective and resulted in a 1:1 mixture of E- and Z- stereoisomeric nitriles (6 and 7).
