77102-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77102-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,0 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77102-93:
(7*7)+(6*7)+(5*1)+(4*0)+(3*2)+(2*9)+(1*3)=123
123 % 10 = 3
So 77102-93-3 is a valid CAS Registry Number.

Limited Methylation of Chlorinated 1,2-Benzenediols to Chlorinated 2-Methoxyphenols
Knuutinen, Juha S.,Tarhanen, Juhani T.
, p. 347 (1981)
The reaction of chlorinated 1,2-benzenediols with dimethyl sulfate in NaOH solution has been investigated and found to result in chlorinated 2-methoxyphenols including three hitherto unknown compounds.Experimental and spectral data (mass, (1)H NMR, (13)C NMR) for all compounds are reported.
