1021187-39-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1021187-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,1,8 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1021187-39:
(9*1)+(8*0)+(7*2)+(6*1)+(5*1)+(4*8)+(3*7)+(2*3)+(1*9)=102
102 % 10 = 2
So 1021187-39-2 is a valid CAS Registry Number.

, p. 555 - 569 (2008/09/20)
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
