Check Digit Verification of cas no

The CAS Registry Mumber 1447829-02-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,8,2 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1447829-02:
(9*1)+(8*4)+(7*4)+(6*7)+(5*8)+(4*2)+(3*9)+(2*0)+(1*2)=188
188 % 10 = 8
So 1447829-02-8 is a valid CAS Registry Number.

Novel synthesis of butyl (S)-2-hydroxybutanoate, the key intermediate of PPARα agonist (R)-K-13675 from butyl (2 S,3 R)-epoxybutanoate and butyl (S)-2,3-epoxypropanoate

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

, p. 1319 - 1324 (2013)

Novel synthetic methods for the production of butyl (S)-2-hydroxybutanoate starting from butyl (2S,3R)-epoxybutanoate or butyl (S)-2,3-epoxypropanoate were established. The former method utilized the regioselective thiolysis of the epoxybutanoate mediated by scandium triflate and subsequent reductive cleavage of the thioether to give butyl (S)-2-hydroxybutanoate with stereochemical retention in quantitative yield. The latter method utilized one-step conversion by a combination of methylmagnesium bromide and copper catalyst in high yield. Georg Thieme Verlag Stuttgart, New York.
