1171248-89-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1171248-89-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,1,2,4 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1171248-89:
(9*1)+(8*1)+(7*7)+(6*1)+(5*2)+(4*4)+(3*8)+(2*8)+(1*9)=147
147 % 10 = 7
So 1171248-89-7 is a valid CAS Registry Number.

Photolysis of 1,2-naphthoquinone in oxygen-doped argon matrix at low temperature
Itoh, Takayoshi,Tatsugi, Jiro,Tomioka, Hideo
, p. 737 - 742 (2009)
Photolysis of 1,2-naphthoquinone (1) in argon matrix either with or without oxygen at 10K was investigated by IR spectroscopy in combination with DFT calculations. The results indicate that 1 gave bis(ketene) 2 as a main product along with a small amount
