Check Digit Verification of cas no

The CAS Registry Mumber 1298022-54-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,8,0,2 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1298022-54:
(9*1)+(8*2)+(7*9)+(6*8)+(5*0)+(4*2)+(3*2)+(2*5)+(1*4)=164
164 % 10 = 4
So 1298022-54-4 is a valid CAS Registry Number.

Nickel-Catalyzed Reductive Cross-Coupling of Aryl Bromides with Vinyl Acetate in Dimethyl Isosorbide as a Sustainable Solvent

Su, Mincong,Huang, Xia,Lei, Chuanhu,Jin, Jian

supporting information, p. 354 - 358 (2022/01/15)

A nickel-catalyzed reductive cross-coupling has been achieved using (hetero)aryl bromides and vinyl acetate as the coupling partners. This mild, applicable method provides a reliable access to a variety of vinyl arenes, heteroarenes, and benzoheterocycles, which should expand the chemical space of precursors to fine chemicals and polymers. Importantly, a sustainable solvent, dimethyl isosorbide, is used, making this protocol more attractive from the point of view of green chemistry.
