22328-44-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22328-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,2 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22328-44:
(7*2)+(6*2)+(5*3)+(4*2)+(3*8)+(2*4)+(1*4)=85
85 % 10 = 5
So 22328-44-5 is a valid CAS Registry Number.

Synthesis of Isotopically Labeled Tri-p-tolylamine

Kesling, Brian D.,Soederberg, Bjoern C.,Gullion, Terry

, p. 1059 - 1068 (2007/10/03)

Three isotopically labeled tri-p-tolylamines, 15N, 15N2D2, and mono-13CH3, have been prepared using zeolite mediated bromination or nitration of toluenes as one of the key steps. The obtained 4-nitrotoluenes were reduced to 4-aminotoluenes, and coupled, v

Asymmetric Synthesis. Mechanism of Asymmetric Catalytic Allylation

Mackenzie, Peter B.,Whelan, John,Bosnich, B.

, p. 2046 - 2054 (2007/10/02)

The mechanism of palladium-assisted asymmetric catalytic allylation has been investigated.It is found that the process involves two primary steps: the oxidative addition of a palladium(0)-phosphine species with an allyl acetate to form diastereomeric ?-al
