134699-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134699-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,6,9 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 134699-81:
(8*1)+(7*3)+(6*4)+(5*6)+(4*9)+(3*9)+(2*8)+(1*1)=163
163 % 10 = 3
So 134699-81-3 is a valid CAS Registry Number.

3-Amino-2-arylpropanoic acids by electrophilic substitution of 2-arylethylamines at the benzylic position
Simig,Schlosser
, p. 1963 - 1964 (2007/10/02)
A reaction sequence consisting of N-pivaloylation, lithiation at the benzylic position, carboxylation and deprotection allows to convert 2-arylethylamines into 3-amino-2-arylpropanoic acids with good yields.
