1046427-59-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1046427-59-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,4,2 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1046427-59:
(9*1)+(8*0)+(7*4)+(6*6)+(5*4)+(4*2)+(3*7)+(2*5)+(1*9)=141
141 % 10 = 1
So 1046427-59-1 is a valid CAS Registry Number.

Parallel kinetic resolution of methyl (RS)-5-tris(phenylthio)methyl-cyclopent-1-ene-carboxylate for the asymmetric synthesis of (1R,2S,5S)- and (1S,2R,5R)-5-methyl-cispentacin

, p. 1356 - 1362 (2008/12/20)

Parallel kinetic resolution of methyl (RS)-5-tris(phenylthio)methyl-cyclopent-1-ene-carboxylate with a 50:50 pseudoenantiomeric mixture of lithium (S)-N-benzyl-N-(α-methylbenzyl)amide and lithium (R)-N-3,4-dimethoxybenzyl-N-(α-methylbenzyl)amide provides an efficient entry to the corresponding homochiral methyl (1R,2S,5S)- and (1S,2R,5R)-2-amino-5-tris(phenylthio)methyl-cyclopentane-carboxylate derivatives in >98% de, with subsequent, sequential desulfurisation with Raney Nickel, N-debenzylation and ester hydrolysis furnishing (1R,2S,5S)- and (1S,2R,5R)-5-methyl-cispentacin in high yield, >98% de and >98% ee.
