537693-68-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 537693-68-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,6,9 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 537693-68:
(8*5)+(7*3)+(6*7)+(5*6)+(4*9)+(3*3)+(2*6)+(1*8)=198
198 % 10 = 8
So 537693-68-8 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.
