Check Digit Verification of cas no

The CAS Registry Mumber 940287-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,0,2,8 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 940287-58:
(8*9)+(7*4)+(6*0)+(5*2)+(4*8)+(3*7)+(2*5)+(1*8)=181
181 % 10 = 1
So 940287-58-1 is a valid CAS Registry Number.

Cobalt-Catalyzed Decarboxylative C-H (Hetero)Arylation for the Synthesis of Arylheteroarenes and Unsymmetrical Biheteroaryls

Li, Yanrong,Qian, Fen,Wang, Mengshi,Lu, Hongjian,Li, Guigen

, p. 5589 - 5592 (2017)

A cobalt-catalyzed decarboxylative cross-coupling reaction of (hetero)aryl carboxylic acids with benzothiazoles or benzoxazoles is reported. This represents a first example of metal-catalyzed decarboxylative C-H heteroarylation of benzo-fused heterocycles. The transformation provides a convenient route, with good yields and functional group tolerance, to various important arylheteroaryl and unsymmetrical biheteroaryl structural motifs.
