Check Digit Verification of cas no

The CAS Registry Mumber 130931-86-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,3 and 1 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130931-86:
(8*1)+(7*3)+(6*0)+(5*9)+(4*3)+(3*1)+(2*8)+(1*6)=111
111 % 10 = 1
So 130931-86-1 is a valid CAS Registry Number.

Biocatalytical Transformations- VI. The 4-Acetamido-cyclopent-2-ene Carboxylate Route Revisited: Synthesis of (+)- and (-)-Aristeromycin

Csuk, Rene,Doerr, Petra

, p. 5789 - 5798 (2007/10/02)

Enantiomerically pure (+)-as well as (-)-aristeromycin can be synthesized starting from (+)- or (-)-butyl (or hexyl) 4-acetamido-cyclopent-2-ene carboxylate; these carboxylates are easily obtained from their corresponding racemates by hydrolysis with the lipase from Candida rugosa.
