159976-46-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159976-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,7 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159976-46:
(8*1)+(7*5)+(6*9)+(5*9)+(4*7)+(3*6)+(2*4)+(1*6)=202
202 % 10 = 2
So 159976-46-2 is a valid CAS Registry Number.

, p. 1171 - 1176 (2007/10/02)
This paper describes the preparation of 2-aryl-8-fluorobenzyl-1,2,4-triazolo[5,1-i]purines 2, starting from 2-aryl-7,8-diamino-1,2,4-triazolo[1,5-c]pyrimidines 9. Our synthetic procedure represents the first example of a feasible approach for the synthesi
