Check Digit Verification of cas no

The CAS Registry Mumber 41417-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,1 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 41417-90:
(7*4)+(6*1)+(5*4)+(4*1)+(3*7)+(2*9)+(1*0)=97
97 % 10 = 7
So 41417-90-7 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

supporting information, p. 23127 - 23131 (2020/10/15)

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.
