1188391-93-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1188391-93-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,3,9 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1188391-93:
(9*1)+(8*1)+(7*8)+(6*8)+(5*3)+(4*9)+(3*1)+(2*9)+(1*3)=196
196 % 10 = 6
So 1188391-93-6 is a valid CAS Registry Number.

A novel synthesis of N-but-3-enyl-α- and β-amino acids
Van Nguyen,Brownlee, Robert T. C.,Hughes, Andrew B.
experimental part, p. 1991 - 1998 (2010/03/24)
N-But-3-enyl-α- and β-amino acids can be prepared by cleaving 1,3-oxazolidin-5-ones and 1,3-oxazinan-6-ones in the presence of allylsilanes and boron trifluoride etherate at room temperature in good to excellent yields. Georg Thieme Verlag Stuttgart.
