Check Digit Verification of cas no

The CAS Registry Mumber 69971-20-6 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 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69971-20:
(7*6)+(6*9)+(5*9)+(4*7)+(3*1)+(2*2)+(1*0)=176
176 % 10 = 6
So 69971-20-6 is a valid CAS Registry Number.

Acetoxy Meldrum's acid: A versatile acyl anion equivalent in the Pd-catalyzed asymmetric allylic alkylation

Trost, Barry M.,Osipov, Maksim,Kaib, Philip S. J.,Sorum, Mark T.

supporting information; experimental part, p. 3222 - 3225 (2011/08/07)

Acetoxy Meldrum's acid can serve as a versatile acyl anion equivalent in the Pd-catalyzed asymmetric allylic alkylation. The reaction of this nucleophile with various meso and racemic electrophiles afforded alkylated products in high yields and enantiopur

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.
