3645-19-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3645-19-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,4 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3645-19:
(6*3)+(5*6)+(4*4)+(3*5)+(2*1)+(1*9)=90
90 % 10 = 0
So 3645-19-0 is a valid CAS Registry Number.

Direct β- and γ-C(sp3)?H Alkynylation of Free Carboxylic Acids**

Ghiringhelli, Francesca,Ghosh, Kiron Kumar,Uttry, Alexander,van Gemmeren, Manuel

, p. 23127 - 23131 (2020)

In this study we report the identification of a novel class of ligands for palladium-catalyzed C(sp3)?H activation that enables the direct alkynylation of free carboxylic acid substrates. In contrast to previous synthetic methods, no introduction/removal of an exogenous directing group is required. A broad scope of acids including both α-quaternary and challenging α-non-quaternary can be used as substrates. Additionally, the alkynylation in the distal γ-position is reported. Finally, this study encompasses preliminary findings on an enantioselective variant of the title transformation as well as synthetic applications of the products obtained.
