200334-62-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 200334-62-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,3,3 and 4 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 200334-62:
(8*2)+(7*0)+(6*0)+(5*3)+(4*3)+(3*4)+(2*6)+(1*2)=69
69 % 10 = 9
So 200334-62-9 is a valid CAS Registry Number.

Synthesis of optically active methadones, LAAM and bufuralol by lipase-catalysed acylations
Hull, Jonathan D.,Scheinmann, Feodor,Turner, Nicholas J.
, p. 567 - 576 (2003)
(R)- and (S)-Methadones and levo-α-acetylmethadol (LAAM) have been synthesised starting from lipase-catalysed acylation of dimethylaminopropan-2-ol. An approach to the synthesis of (R)-bufuralol is also presented.
