1037464-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1037464-52-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,7,4,6 and 4 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1037464-52:
(9*1)+(8*0)+(7*3)+(6*7)+(5*4)+(4*6)+(3*4)+(2*5)+(1*2)=140
140 % 10 = 0
So 1037464-52-0 is a valid CAS Registry Number.

Synthesis of 6-ethynylpurine derivatives
Nagy, András,Kotschy, András
, p. 3782 - 3784 (2008/09/21)
A series of 6-(arylethynyl)purine derivatives are synthesized from the corresponding 6-halopurines via sequential and 'one-pot' Sonogashira-coupling reactions. The nature of the acetylene source was found to have a profound influence on the efficiency of
