Check Digit Verification of cas no

The CAS Registry Mumber 1628868-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,8,8,6 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1628868-22:
(9*1)+(8*6)+(7*2)+(6*8)+(5*8)+(4*6)+(3*8)+(2*2)+(1*2)=213
213 % 10 = 3
So 1628868-22-3 is a valid CAS Registry Number.

Ligand-free copper-catalyzed cross-coupling reaction of alkynes with aryl iodides and vinyl halides

Tsai, Wan-Ting,Lin, Yun-Yung,Chen, Yi-An,Lee, Chin-Fa

supporting information, p. 443 - 447 (2014/03/21)

A copper-catalyzed cross-coupling reaction of alkynes with aryl iodides is described. The system tolerates a broad range of functional groups and enables the sterically demanding substrates presented during the catalysis with only 5-10 mol% of Cu2O as the catalyst.
