92669-90-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92669-90-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,6,6 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 92669-90:
(7*9)+(6*2)+(5*6)+(4*6)+(3*9)+(2*9)+(1*0)=174
174 % 10 = 4
So 92669-90-4 is a valid CAS Registry Number.

Dilithiation of Aromatic Ethers
Crowther, G. P.,Sundberg, Richard J.,Sarpeshkar, Ashok M.
, p. 4657 - 4663 (2007/10/02)
The lithiations of anisole and all the isomeric dimethoxy- and trimethoxybenzenes with 2-5 equiv of n-butyllithium/TMEDA complex have been investigated under a variety of reaction conditions.Anisole and m-dimethoxybenzene do not undergo dilithiatian, but
