143076-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143076-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,0,7 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143076-21:
(8*1)+(7*4)+(6*3)+(5*0)+(4*7)+(3*6)+(2*2)+(1*1)=105
105 % 10 = 5
So 143076-21-5 is a valid CAS Registry Number.

Enantiospecific synthesis of R- and S-5,6-dihydroxy-2-(N,N-di-n-propylamino)tetralins from serine
Baxter,Murray,Taylor
, p. 2331 - 2334 (1992)
The first enantiospecific synthesis of 5,6-dihydroxy-2-(N,N-di-n-propylamino)tetralin [5,6-(HO)2DPAT] is reported. Starting from D- or L-serine either enantiomer is readily available in high optical purity.
