Check Digit Verification of cas no
The CAS Registry Mumber 500731-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,7,3 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 500731-91:
(8*5)+(7*0)+(6*0)+(5*7)+(4*3)+(3*1)+(2*9)+(1*1)=109
109 % 10 = 9
So 500731-91-9 is a valid CAS Registry Number.

Ni/Cu-Catalyzed Defluoroborylation of Fluoroarenes for Diverse C-F Bond Functionalizations
Niwa, Takashi,Ochiai, Hidenori,Watanabe, Yasuyoshi,Hosoya, Takamitsu
, p. 14313 - 14318 (2015/11/27)
Ni/Cu-catalyzed transformation of fluoroarenes to arylboronic acid pinacol esters via C-F bond cleavage has been achieved. Further versatile derivatization of an arylboronic ester has allowed for the facile two-step conversion of a fluoroarene to diverse functionalized arenes, demonstrating the synthetic utility of the method.
