3009-45-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3009-45-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,0 and 9 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3009-45:
(6*3)+(5*0)+(4*0)+(3*9)+(2*4)+(1*5)=58
58 % 10 = 8
So 3009-45-8 is a valid CAS Registry Number.

Azo polymers for reversible optical storage. 8. the effect of polarity of the azobenzene groups
Ho,Natansohn,Barrett,Rochon
, p. 1773 - 1778 (1995)
Poly[4′-[[(2-methacryloyloxy)ethyl ]ethylamino]azobenzene] (pMAEA) was prepared. Its reversible optical storage properties were studied and compared with the properties of previously reported poly[4-(2-methacryloyloxy) ethylazobenzene] (pMEA) and poly[4-n
