Check Digit Verification of cas no

The CAS Registry Mumber 3938-13-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 3938-13:
(6*3)+(5*9)+(4*3)+(3*8)+(2*1)+(1*3)=104
104 % 10 = 4
So 3938-13-4 is a valid CAS Registry Number.

1,3-Halogen shift of 2-halogeno-4,5-dimethylphenols following oxidation with Fremy's salt

Jacobs, A. W. C. M.,Maat, L.

, p. 183 - 185 (2007/10/02)

Oxidation of 2-bromo-6-deuterio-4,5-dimethylphenol with Fremy's salt, followed by in situ reduction, yielded mainly 3-bromo-4,5-dimethylpyrocatechol, which affords evidence for a 1,3-bromine shift during the oxidation.The same treatment of 2-chloro-4,5-di
