Definition
ChEBI: An aspartic acid derivative that is L-aspartic acid in which one of the amine hydrogens is substituted by a 9-beta-D-ribofuranosyl-9H-purin-6-yl group.
Check Digit Verification of cas no
The CAS Registry Mumber 4542-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,4 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4542-23:
(6*4)+(5*5)+(4*4)+(3*2)+(2*2)+(1*3)=78
78 % 10 = 8
So 4542-23-8 is a valid CAS Registry Number.

An Unambiguous Synthesis of Adenylosuccinic Acid and its Constituent Nucleoside
Buck, Ildiko M.,Reese, Colin B.
, p. 2937 - 2942 (2007/10/02)
6-(4-Chlorophenylthio)-9-(2,3-O-cyclopentylidene-β-D-ribofuranosyl)-9H-purine (7) is prepared from 6-chloro-9-(2,3,5-tri-O-acetyl-β-D-ribofuranosyl)-9H-purine (5) in three steps and is then converted, by treatment with 3-chloroperbenzoic acid, into the corresponding sulphoxide (9) and crystalline sulphone (8) in ca. 88 and 65percent isolated yield, respectively.When the sulphoxide (9) is heated with dibenzyl L-aspartate in N,N-dimethylacetamide solution at 70-75 deg C for 28 hr, compound (11) is obtained in ca. 70percent isolated yield.Removal of the protecting groups from compound (11) gives N--L-aspartic acid (3) as a crystalline solid in ca. 68percent yield; phosphorylation of compound (11) with dibenzyl phosphorochloridate and removal of the protecting groups gives adenylosuccinic acid (1), isolated as its ammonium salt, in ca. 66percent yield.When the sulphone (8) is converted via compound (11) into the diacids (3) and (1), the products obtained appear to be contaminated with the D-acids (12) and (14), respectively, which are diastereomers of compounds (3) and (1).
