82120-24-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82120-24-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,2 and 0 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82120-24:
(7*8)+(6*2)+(5*1)+(4*2)+(3*0)+(2*2)+(1*4)=89
89 % 10 = 9
So 82120-24-9 is a valid CAS Registry Number.

SYNTHESIS OF NON-K-REGION ORTHO-QUINONES OF POLYCYCLIC AROMATIC HYDROCARBONS FROM CYCLIC KETONES
Platt, Karl L.,Oesch, Franz
, p. 163 - 166 (2007/10/02)
Non-K-region o-quinones of polycyclic aromatic hydrocarbons are prepared in four steps from cyclic ketones via dehydrogenation of tetrahydrodiols with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone.
