Check Digit Verification of cas no

The CAS Registry Mumber 21775-43-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,7 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21775-43:
(7*2)+(6*1)+(5*7)+(4*7)+(3*5)+(2*4)+(1*3)=109
109 % 10 = 9
So 21775-43-9 is a valid CAS Registry Number.

Tethered NHC Ligands for Stereoselective Alkyne Semihydrogenations

Pape, Felix,Teichert, Johannes F.

, p. 2470 - 2482 (2017)

A copper(I)-catalyzed semihydrogenation of internal alkynes has been developed. A variety of oxygen- and nitrogen-tethered N-heterocyclic carbene (NHC) complexes have been investigated, leading to a highly Z-selective transformation. The catalyst is generated from inexpensive copper(I) chloride in situ and allows catalytic semihydrogenation down to 10 bar H2.
