172587-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172587-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,5,8 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 172587-40:
(8*1)+(7*7)+(6*2)+(5*5)+(4*8)+(3*7)+(2*4)+(1*0)=155
155 % 10 = 5
So 172587-40-5 is a valid CAS Registry Number.

Synthesis and configurational assignment of (R) and (S)-2-bromohexadecanoic acids
Hernanz,Camps,Guerrero,Delgado
, p. 2291 - 2298 (2007/10/03)
Synthesis of both enantiomers of 2-bromohexadecanoic acid is described by diastereoselective bromination of esters (+) and (-)-3 followed by removal of the chiral auxiliary. The absolute configuration of the acids is confirmed by an independent chemical s
