Check Digit Verification of cas no
The CAS Registry Mumber 657-47-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 657-47:
(5*6)+(4*5)+(3*7)+(2*4)+(1*7)=86
86 % 10 = 6
So 657-47-6 is a valid CAS Registry Number.

HYDROLYSIS OF AROMATIC SULFONIC ACIDS UNDER THERMODYNAMIC CONTROL OF THE REACTION
Krylov, E. N.,Volgina, L. V.,Isaeva, G. Yu.
, p. 1129 - 1133 (2007/10/02)
Linear mathematical models which describe the hydrolysis of alkyl- and halobenzenesulfonyl acids under the conditions for their isomerization in sulfuric acid have been obtained by the method of mathematical experiment planning.The value of the effective rate constants of hydrolysis calculated according to the models for comparative conditions (150 deg C, 3 moles of 85percent sulfuric acid) were used to obtain the correlation between log kh and the ? constants of the substituents.The correlation corresponds the electrophilic nature of the hydrolysis process (ρ = -4.69).The strong influence of the electronic effects of the substituents on the rate of hydrolysis is an indication of the development of a considerable positive charge on the reaction center in the transition state.
