Check Digit Verification of cas no

The CAS Registry Mumber 1380341-57-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,3,4 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1380341-57:
(9*1)+(8*3)+(7*8)+(6*0)+(5*3)+(4*4)+(3*1)+(2*5)+(1*7)=140
140 % 10 = 0
So 1380341-57-0 is a valid CAS Registry Number.

Ni-catalyzed reductive coupling of α-halocarbonyl derivatives with vinyl bromides

Qiu, Canbin,Yao, Ken,Zhang, Xinghua,Gong, Hegui

, p. 11332 - 11335 (2016)

This work describes the vinylation of α-halo carbonyl compounds with vinyl bromides under Ni-catalyzed reductive coupling conditions. While aryl-conjugated vinyl bromides entail pyridine as the sole labile ligand, the alkyl-substituted vinyl bromides require both bipyridine and pyridine as the co-ligands.
