Check Digit Verification of cas no

The CAS Registry Mumber 1055325-40-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,5,3,2 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1055325-40:
(9*1)+(8*0)+(7*5)+(6*5)+(5*3)+(4*2)+(3*5)+(2*4)+(1*0)=120
120 % 10 = 0
So 1055325-40-0 is a valid CAS Registry Number.

A practical synthesis of the PPARα agonist, (R)-K-13675, starting from (S)-2-hydroxybutyrolactone

Yamazaki, Yukiyoshi,Araki, Takaaki,Koura, Minoru,Shibuya, Kimiyuki

, p. 8155 - 8158 (2008)

A practical synthesis of optically pure PPARα agonist, (R)-K-13675, is described. This process is based on the use of (S)-2-hydroxybutyrolactone, which can be transformed into the requisite n-butyl (S)-2-hydroxybutanoate in an efficient manner. A key reaction is the etherification between the phenol and n-butyl (S)-2-trifluoromethanesulfonyloxybutanoate to give the phenyl ether in excellent yield without loss of optical purity.
