Check Digit Verification of cas no
The CAS Registry Mumber 41108-87-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,1,0 and 8 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 41108-87:
(7*4)+(6*1)+(5*1)+(4*0)+(3*8)+(2*8)+(1*7)=86
86 % 10 = 6
So 41108-87-6 is a valid CAS Registry Number.

Preparation of β-aminoesters from ketene silyl acetals and N-(alkylamino)benzotriazoles
Katritzky,Shobana,Harris
, p. 3999 - 4002 (2007/10/02)
A wide variety of β-aminoesters are prepared in good yields by the reaction of lithium ester enolates derived from ketene silyl acetals with N-(alkylamino)benzotriazoles. The secondary β-aminoesters readily cyclize to β-lactams (2-azetidinones) on deprotonation.
