Check Digit Verification of cas no

The CAS Registry Mumber 134895-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,9 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134895-48:
(8*1)+(7*3)+(6*4)+(5*8)+(4*9)+(3*5)+(2*4)+(1*8)=160
160 % 10 = 0
So 134895-48-0 is a valid CAS Registry Number.

Enantioselective Synthesis of (S)-2-Methyl-1-alkanols via Bakers'Yeast Mediated Reduction of α-Methyl-2-thiophenepropenals

Hoegberg, Hans-Erik,Hedenstroem, Erik,Faegerhag, Jonas,Servi, Stefano

, p. 2052 - 2059 (1992)

The bakers'yeast mediated enantioselective reductions of some α-methyl-5-(1-alkyl)-2-thiophenepropenals 3 are described.These furnished (S)-β-methyl-5-(1-alkyl)-2-thiophenepropanols 5 in good to high enantiomeric excesses (76-98percent ee).An alternative approach to (S)-β-methyl-5-(1-alkyl)-2-thiophenepropanols 5d-f (98percent ee) is also described.Raney nickel reduction of their acetates, followed by hydrolysis, provided (S)-2-methyl-1-alkanols 2b-f of unchanged optical purities.
