40452-14-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 40452-14-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,5 and 2 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 40452-14:
(7*4)+(6*0)+(5*4)+(4*5)+(3*2)+(2*1)+(1*4)=80
80 % 10 = 0
So 40452-14-0 is a valid CAS Registry Number.

Phenanthrylalkanoic acids, V. A useful access to α-methylphenanthreneacetic acids
Balo,Fernandez,Gomez,Gonzalez,Lopez
, p. 967 - 969 (2007/10/02)
A very simple one-pot monomethylation of phenanthreneacetic acids 2 or of their methyl esters 1 yields α-methylphenanthreneacetic acids 3 in good yield. Alternatively, the process may be extended to the preparation of the corresponding α-arylisobutyric acids 4.
