Check Digit Verification of cas no

The CAS Registry Mumber 1826-19-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,2 and 6 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1826-19:
(6*1)+(5*8)+(4*2)+(3*6)+(2*1)+(1*9)=83
83 % 10 = 3
So 1826-19-3 is a valid CAS Registry Number.

Nickel-catalyzed Suzuki-Miyaura couplings in green solvents

Ramgren, Stephen D.,Hie, Liana,Ye, Yuxuan,Garg, Neil K.

supporting information, p. 3950 - 3953 (2013/09/02)

The nickel-catalyzed Suzuki-Miyaura coupling of aryl halides and phenol-derived substrates with aryl boronic acids using green solvents, such as 2-Me-THF and tert-amyl alcohol, is reported. This methodology employs the commercially available and air-stable precatalyst, NiCl2(PCy 3)2, and gives biaryl products in synthetically useful to excellent yields. Using this protocol, bis(heterocyclic) frameworks can be assembled efficiently.
