Check Digit Verification of cas no

The CAS Registry Mumber 63904-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,0 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 63904-72:
(7*6)+(6*3)+(5*9)+(4*0)+(3*4)+(2*7)+(1*2)=133
133 % 10 = 3
So 63904-72-3 is a valid CAS Registry Number.

Remote sp2C-H Carboxylation via Catalytic 1,4-Ni Migration with CO2

B?rjesson, Marino,Duan, Yaya,Janssen-Müller, Daniel,Martin, Ruben,Sahoo, Basudev,Wang, Xueqiang

supporting information, p. 16234 - 16239 (2020/10/09)

A remote catalytic reductive sp2 C-H carboxylation of arenes with CO2 (1 bar) via 1,4-Ni migration is disclosed. This protocol constitutes the first catalytic 1,4-Ni migration reported to date, thus offering new vistas in the Ni-catalyzed reductive coupling arena while providing an unconventional new platform for incorporating electrophilic sites at remote sp2 C-H linkages.
