199122-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199122-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,1,2 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 199122-40:
(8*1)+(7*9)+(6*9)+(5*1)+(4*2)+(3*2)+(2*4)+(1*0)=152
152 % 10 = 2
So 199122-40-2 is a valid CAS Registry Number.

Synthesis of enantiomerically pure aziridine-2-imides by cyclization of chiral 3-benzyloxyamino imide enolates
Bongim,Cardillo,Gentilucci,Tomasini
, p. 9148 - 9159 (2007/10/03)
Aziridine-2-imides are prepared both in high yield and high diastereoselectivity from chiral 3'-benzyloxyamino imides 2, 3, and 8 by treatment with triethylamine in the presence of either TiCl4 or AlMe2Cl. 2 and 3 are easily obtained
