923921-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 923921-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,3,9,2 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 923921-75:
(8*9)+(7*2)+(6*3)+(5*9)+(4*2)+(3*1)+(2*7)+(1*5)=179
179 % 10 = 9
So 923921-75-9 is a valid CAS Registry Number.

Palladium-catalyzed direct ortho -alkynylation of aromatic carboxylic acid derivatives
Ano, Yusuke,Tobisu, Mamoru,Chatani, Naoto
, p. 354 - 357 (2012/03/09)
The palladium-catalyzed direct alkynylation of C-H bonds in aromatic carboxylic acid derivatives is described. The use of 8-aminoquinoline as a directing group facilitates the alkynylation of an electronically diverse range of C(sp2)-H bonds.
