Check Digit Verification of cas no

The CAS Registry Mumber 1619261-38-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,9,2,6 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1619261-38:
(9*1)+(8*6)+(7*1)+(6*9)+(5*2)+(4*6)+(3*1)+(2*3)+(1*8)=169
169 % 10 = 9
So 1619261-38-9 is a valid CAS Registry Number.

Synthesis of (S)-2-amino-7-methoxytetralin and isoindolo[1,2-a]isoquinolinone derivatives from l-aspartic acid

Aaseng, Jon Erik,Gautun, Odd R.

, p. 5057 - 5063 (2014/12/10)

This paper describes a new total synthesis for (S)-2-amino-7-methoxytetralin, (S)-7-MeO-AT, from l-aspartic acid in an overall yield of 10% over nine steps. The major loss was ascribed to a key intramolecular Friedel-Crafts cyclization step, which afforded up to 36% yield. Attempts to perform a Friedel-Crafts cyclization of an intermediate phthalimide protected amino alcohol 13 did not give the desired protected (S)-7-MeO-AT. On the other hand, two new isoindolo[1,2-a]isoquinolinone derivatives 14 and 15, were isolated in 21 and 11% yield, respectively. The yield of 15 was improved to 70%.
