1433782-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1433782-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,3,7,8 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1433782-33:
(9*1)+(8*4)+(7*3)+(6*3)+(5*7)+(4*8)+(3*2)+(2*3)+(1*3)=162
162 % 10 = 2
So 1433782-33-2 is a valid CAS Registry Number.

Metal-free aerobic oxidation of benzazole derivatives
Dos Santos, Aurelie,El Kaim, Laurent,Grimaud, Laurence

2-Benzyl benzothiazoles and benzimidazoles are easily oxidized under air and basic conditions to give the corresponding ketones in good yields. The use of palladium acetate as a catalyst has little effect and even gives, in some cases, much lower yields.
