Check Digit Verification of cas no

The CAS Registry Mumber 907192-58-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,7,1,9 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 907192-58:
(8*9)+(7*0)+(6*7)+(5*1)+(4*9)+(3*2)+(2*5)+(1*8)=179
179 % 10 = 9
So 907192-58-9 is a valid CAS Registry Number.

Enantioselective synthesis of the PPARα agonist (R)-K-13675 via (S)-2-hydroxybutyrolactone

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

, p. 1017 - 1022 (2008)

Enantioselective synthesis of enantiomerically pure PPARα agonist (R)-K-13675 can be achieved starting from (S)-2-hydroxybutyrolactone. An important intermediate, 2-(aryloxy)butyrolactone, was prepared by reaction of the phenol with (S)-2-hydroxybutyrolactone in excellent yield without loss of enantiomeric purity using the Mitsunobu reaction, followed by conversion into the 2-(aryloxy)butanoic acid via the 2-(aryloxy)-4-iodobutanoate by cleavage of the lactone on exposure to iodotrimethylsilane, followed by hydrogenolysis and hydrolysis.
