70644-35-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 70644-35-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,4 and 4 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70644-35:
(7*7)+(6*0)+(5*6)+(4*4)+(3*4)+(2*3)+(1*5)=118
118 % 10 = 8
So 70644-35-8 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.
