108886-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 108886-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,8,8,8 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 108886-90:
(8*1)+(7*0)+(6*8)+(5*8)+(4*8)+(3*6)+(2*9)+(1*0)=164
164 % 10 = 4
So 108886-90-4 is a valid CAS Registry Number.

A concise synthesis of 4′-O-methyl honokiol
Denton, Ross M.,Scragg, James T.,Saska, Jan
supporting information; experimental part, p. 2554 - 2556 (2011/06/21)
A concise and protecting group free synthesis of the naturally occurring neolignan 4′-O-methyl honokiol is developed. The key biaryl bond is constructed by 1,2-addition of an aryl Grignard reagent to a dienone followed by rearrangement.
