83297-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 83297-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,2,9 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83297-77:
(7*8)+(6*3)+(5*2)+(4*9)+(3*7)+(2*7)+(1*7)=162
162 % 10 = 2
So 83297-77-2 is a valid CAS Registry Number.

The (1)H NMR of 28 substituted phenazines have been measured and analysed with computer assistance.Substituent increments of chemical shifts were calculated for methoxy, carbomethoxy and methyl derivatives.The influence of these substituents on coupling constants has been examined.
