Check Digit Verification of cas no
The CAS Registry Mumber 142176-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,1,7 and 6 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 142176-64:
(8*1)+(7*4)+(6*2)+(5*1)+(4*7)+(3*6)+(2*6)+(1*4)=115
115 % 10 = 5
So 142176-64-5 is a valid CAS Registry Number.

Asymmetric synthesis of both enantiomers of methyl and t-butyl 3-hydroxybutyrates monitored by optically active sulfoxides
Solladie, Guy,Almario, Antonio
, p. 2477 - 2480 (2007/10/02)
Methyl and t-butyl (R) and (S) 3-hydroxybutyrates were prepared by stereoselective reduction of (R) 4-[p-tolylsulfinyl]-3-oxobutyrate, readily available in one step from (-)(S) menthyl p-toluene sulfinate.
