1335199-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1335199-99-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,1,9 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1335199-99:
(9*1)+(8*3)+(7*3)+(6*5)+(5*1)+(4*9)+(3*9)+(2*9)+(1*9)=179
179 % 10 = 9
So 1335199-99-9 is a valid CAS Registry Number.

Aziridines are important synthetic intermediates which readily undergo ring-opening reactions. It is demonstrated that electron-rich phosphines are efficient catalysts for the regioselective rearrangement of N-acylaziridines to oxazolines. The reactions o
