125564-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125564-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,5,6 and 4 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125564-93:
(8*1)+(7*2)+(6*5)+(5*5)+(4*6)+(3*4)+(2*9)+(1*3)=134
134 % 10 = 4
So 125564-93-4 is a valid CAS Registry Number.

An asymmetric synthesis of (-)-tetrahydrolipstatin
Pommier,Pons
, p. 1294 - 1300 (2007/10/02)
A key step in a short asymmetric synthesis of the potent pancreatic lipase inhibitor (-)-tetrahydrolipstatin (2) is a Lewis acid-catalysed [2 + 2] cycloaddition of n-hexyl(trimethylsilyl)ketene (5) to (R)-3-(tertbutyldimethylsilyloxy)tetradecanal (4a).
