Check Digit Verification of cas no
The CAS Registry Mumber 6627-34-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,2 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6627-34:
(6*6)+(5*6)+(4*2)+(3*7)+(2*3)+(1*4)=105
105 % 10 = 5
So 6627-34-5 is a valid CAS Registry Number.

Construction of interconnected acidity functions based on ortho substituted anilines and N-methylanilines as indicators

The log I values of 15 mainly ortho substituted derivatives of aniline and N-methylaniline have been measured spectrophotometrically in sulfuric, perchloric, and methanesulfonic acids. A new algorithm has been suggested for construction of acidity functions enabling simultaneous and independent construction of acidity functions in various media under the condition of equal values of pKa of the same indicators in the given media. The so-called interconnected acidity functions have been constructed with using this algorithm and the log I values measured in the above media, and the pKa values have been calculated. The resulting acidity functions and pKa values agree well with the corresponding literature data.
