39013-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39013-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,0,1 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 39013-80:
(7*3)+(6*9)+(5*0)+(4*1)+(3*3)+(2*8)+(1*0)=104
104 % 10 = 4
So 39013-80-4 is a valid CAS Registry Number.

The effective synthesis of the azathioprine analogs - 2-subsituted derivatives of 7-methyl-6-(1-methyl-4-nitroimidazol-5-ylthio)purines 5 has been achieved by the reaction of 2-subsituted 6-purinethiones 4 with 5-chloro-l-methyl-4-nitroimidazole in ethano
