Check Digit Verification of cas no

The CAS Registry Mumber 189032-31-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,0,3 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 189032-31:
(8*1)+(7*8)+(6*9)+(5*0)+(4*3)+(3*2)+(2*3)+(1*1)=143
143 % 10 = 3
So 189032-31-3 is a valid CAS Registry Number.

Brewers' yeast-mediated synthesis of (1S,2S)-1-(2-thienyl)-1,2-propanediol and a study on the lipase-catalyzed regioselective introduction of acyl protective group to the diol moiety

, p. 331 - 338 (1997)

Reductive homologation of thiophenecarboxyaldehyde mediated by brewers' yeast and subsequent recrystallization provided (1S,2S)-1-(2-thienyl)-1,2-propanediol in 29% yield. A Pseudomonas lipase-catalyzed acetylation preferentially occurred on the hydroxyl group at C-1 position of the diol.
