134869-90-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134869-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,6 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134869-90:
(8*1)+(7*3)+(6*4)+(5*8)+(4*6)+(3*9)+(2*9)+(1*0)=162
162 % 10 = 2
So 134869-90-2 is a valid CAS Registry Number.

A facile synthesis of functionalized 4-benzylpyridines by using mixed copper, zinc benzylic organometallics
Chia,Shiao
, p. 2033 - 2034 (2007/10/02)
A general approach by use of highly functionalized mixed copper zinc, benzylic organometallics to react with N-ethoxycarbonylpyridinium chloride to give regioselectively 4-benzylpyridines after oxygen oxidation in 30-75% yield is described.
