Check Digit Verification of cas no

The CAS Registry Mumber 38045-28-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,0,4 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 38045-28:
(7*3)+(6*8)+(5*0)+(4*4)+(3*5)+(2*2)+(1*8)=112
112 % 10 = 2
So 38045-28-2 is a valid CAS Registry Number.

Barbier–Negishi Coupling of Secondary Alkyl Bromides with Aryl and Alkenyl Triflates and Nonaflates

Zhang, Ke-Feng,Christoffel, Fadri,Baudoin, Olivier

, p. 1982 - 1986 (2018)

A mild and practical Barbier–Negishi coupling of secondary alkyl bromides with aryl and alkenyl triflates and nonaflates has been developed. This challenging reaction was enabled by the use of a very bulky imidazole-based phosphine ligand, which resulted in good yields as well as good chemo- and site selectivities for a broad range of substrates at room temperature and under non-aqueous conditions. This reaction was extended to primary alkyl bromides by using an analogous pyrazole-based ligand.
