22247-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22247-83-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,4 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 22247-83:
(7*2)+(6*2)+(5*2)+(4*4)+(3*7)+(2*8)+(1*3)=92
92 % 10 = 2
So 22247-83-2 is a valid CAS Registry Number.

SYNTHESIS AND N-ALKYLATION OF 6-BENZYLOXYPURINE UNDER PHASE-TRANSFER CONDITIONS
Ramzaeva, N.,Goldberg, Yu.,Alksnis, E.,Lidaks, M.
, p. 1669 - 1676 (2007/10/02)
Synthesis of 6-benzyloxypurine and its N-alkylation under phase-transfer conditions represents a high-yield and simple procedure for the preparation of 9- and 7-substituted 6-benzyloxypurines and, therefore, related hypoxanthines.
