Check Digit Verification of cas no
The CAS Registry Mumber 71154-34-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,1,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71154-34:
(7*7)+(6*1)+(5*1)+(4*5)+(3*4)+(2*3)+(1*4)=102
102 % 10 = 2
So 71154-34-2 is a valid CAS Registry Number.

The acid dissociation constants of some 2-substituted thiophene-3-carboxylic acids (I: X equals OMe, Me, SMe, H, F, Cl, Br, SOMe, SO//2Me and CN) in water, at 25 degree , have been measured and correlated by means of the Yukawa-Tsuno equation ( sigma plus 1. 80, r** plus 0. 32, R 0. 996), confirming the difference, probably linked to the geometry of the five-membered ring, from the situation observed for ortho-substituted benzoic acids. The data obtained are discussed and compared with those of other substituted thiophene-carboxylic acids.
