Check Digit Verification of cas no

The CAS Registry Mumber 69979-45-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,7 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 69979-45:
(7*6)+(6*9)+(5*9)+(4*7)+(3*9)+(2*4)+(1*5)=209
209 % 10 = 9
So 69979-45-9 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 (1995)

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.
