196502-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 196502-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,6,5,0 and 2 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 196502-01:
(8*1)+(7*9)+(6*6)+(5*5)+(4*0)+(3*2)+(2*0)+(1*1)=139
139 % 10 = 9
So 196502-01-9 is a valid CAS Registry Number.

, p. 771 - 776 (1997)
New di-o-quinones of the biphenyl series, namely, 2,2′-dialkyl-5,5′-di-tert-butylbiphenyl-3,4,3′,4′- diquinones, were synthesized. Their structures were established by IR and NMR spectroscopy. The molecular structure of 2,2′-dimethyl-5,5′-di-tert-butylbip
