490-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 490-19-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 490-19:
(5*4)+(4*9)+(3*0)+(2*1)+(1*9)=67
67 % 10 = 7
So 490-19-7 is a valid CAS Registry Number.

Electrochemical methoxylation of cinnamic acid and its derivatives
Il'chibaeva,Kagan,Tomilov
, p. 1592 - 1595 (2001)
Electrochemical methoxylation of cinnamic acid is accompanied by decarboxylation and yields 1,1,2-trimethoxy-2-phenylethane through formation of γ-truxillic acid in the initial stage. Under the same conditions methyl cinnamate and cinnamamide give rise to
