144216-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144216-54-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,1 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144216-54:
(8*1)+(7*4)+(6*4)+(5*2)+(4*1)+(3*6)+(2*5)+(1*4)=106
106 % 10 = 6
So 144216-54-6 is a valid CAS Registry Number.

Efficient Synthesis of 3H,5H-Pyrrolopyrimidin-4-one
Brakta, Mohamed,Daves, G. Doyle
, p. 1883 - 1884 (2007/10/02)
Palladium-catalysed cross-coupling of 4-iodo-6-methoxy-5-nitropyrimidine and trimethyl(tributylstannylethynyl)silane to form the corresponding 4-trimethylsilylethynylpyrimidine and subsequent construction of an annellated pyrrolo ring provides an efficient route to the pyrrolopyrimidine system.
