1258740-37-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1258740-37-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,8,7,4 and 0 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1258740-37:
(9*1)+(8*2)+(7*5)+(6*8)+(5*7)+(4*4)+(3*0)+(2*3)+(1*7)=172
172 % 10 = 2
So 1258740-37-2 is a valid CAS Registry Number.

Synthesis of substituted (S)-2-aminotetralins via ring-opening of aziridines prepared from l-aspartic acid β-tert-butyl ester

Aaseng, Jon Erik,Gautun, Odd R.

scheme or table, p. 8982 - 8991 (2011/01/04)

This paper describes the total synthesis of the hydrochloride salts of (2S)-2-amino-7-methoxytetralin (21-HCl) and (2S)-2-amino-6-fluoro-7- methoxytetralin (ST1214), from a common enantiomerically pure aziridine 4b, which was available from l-aspartic acid β-tert-butyl ester. The synthesis of 21-HCl and ST1214 proceeded in nine steps and 5 and 6% overall yields, respectively. Key steps are the regioselective ring-opening of 4b with ArMgBr/CuBr·SMe2 and the intramolecular Friedel-Crafts cyclisation providing α-tetralone. Substituted naphthalenes were formed as side products in the latter reaction.
