Check Digit Verification of cas no

The CAS Registry Mumber 117097-84-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,0,9 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 117097-84:
(8*1)+(7*1)+(6*7)+(5*0)+(4*9)+(3*7)+(2*8)+(1*4)=134
134 % 10 = 4
So 117097-84-4 is a valid CAS Registry Number.

Formation of single diastereomers of β-hydroxy-sulfoxides by biotransformation of β-ketosulfides using Helminthosporium species NRRL 4671

Holland, Herbert L.,Ihasz, Nancy,Lounsbery, Brendan J.

, p. 640 - 642 (2007/10/03)

Single biotransformations of 1-(phenylthio)-2-propanone and 1-(p-methoxyphenylthio)-2-propanone by the fungus Helminthosporium species NRRL 4671 resulted in both sulfur oxidation to the sulfoxide and carbonyl reduction to the alcohol. The corresponding (SS,SC)-1-sulfinyl-2-propanols were obtained as single diastereomers following simple crystallization.
