Check Digit Verification of cas no

The CAS Registry Mumber 1042719-89-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,7,1 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1042719-89:
(9*1)+(8*0)+(7*4)+(6*2)+(5*7)+(4*1)+(3*9)+(2*8)+(1*9)=140
140 % 10 = 0
So 1042719-89-0 is a valid CAS Registry Number.

Modified palladium-catalyzed regioselective ortho-arylation of sp2 C-H bond substrates with a low catalyst loading

Yang, Fan,Wu, Yangjie,Li, Yanan,Wang, Biao,Zhang, Junli

experimental part, p. 914 - 919 (2009/04/07)

A novel and generally applicable system for ortho-arylation of a broad range of sp2 C-H bond substrates such as arylated benzoxazoles, acylated anilines, and pyridines has been developed. The arylation was performed in trifluoroacetic acid (TFA
