80884-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80884-53-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,8,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80884-53:
(7*8)+(6*0)+(5*8)+(4*8)+(3*4)+(2*5)+(1*3)=153
153 % 10 = 3
So 80884-53-3 is a valid CAS Registry Number.

From 1b, 1c and 1d no "1,4-oxazines" are available under dehydrating conditions.Only reaction of 1c with PPA at room temperature yields 7, while 1d in dependence of the reaction time with PPA at 100 deg C undergoes cyclisation to the indoles 3b and 3c and
