181226-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 181226-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,2,2 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 181226-89:
(8*1)+(7*8)+(6*1)+(5*2)+(4*2)+(3*6)+(2*8)+(1*9)=131
131 % 10 = 1
So 181226-89-1 is a valid CAS Registry Number.

Nickel-catalyzed methylation of aryl halides/tosylates with methyl tosylate
Wang, Jiawang,Zhao, Jianhong,Gong, Hegui
supporting information, p. 10180 - 10183 (2017/09/23)
This work describes the cross-electrophile methylation of aryl bromides and aryl tosylates with methyl tosylate. The mild reaction conditions allow effective methylation of a wide set of heteroaryl electrophiles and dimethylation of dibromoarenes.
