Check Digit Verification of cas no
The CAS Registry Mumber 43033-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,3 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 43033-72:
(7*4)+(6*3)+(5*0)+(4*3)+(3*3)+(2*7)+(1*2)=83
83 % 10 = 3
So 43033-72-3 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 (2007/10/03)
(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.
