Check Digit Verification of cas no
The CAS Registry Mumber 56919-17-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,1 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 56919-17:
(7*5)+(6*6)+(5*9)+(4*1)+(3*9)+(2*1)+(1*7)=156
156 % 10 = 6
So 56919-17-6 is a valid CAS Registry Number.

Aromatic sulfonation 85. Halogen directing and steric effects in the sulfonation of the twelve halogenotoluenes and some related compounds

The isomer distributions for the sulfonation of the twelve halogenotoluenes and some trisubstituted halogenomethylbenzenes, with both 98.4 percent H2SO4 at 25 deg C and sulfur trioxide in nitromethane at 0 deg C, have been determined and found to be very similar.The predominantly para-directing effect of the halogen substituent dominates over that of the methyl substituent: with the 2-halogenotoluenes, the degree of 5-substitution decreases from >/= 90 percent for the fluoro to 50 percent for the iodo compound.The 2- to 3-sulfonation ratio of the 4-halogenotoluenes strongly increases on going from fluorine (0.5) to iodine (7).The ratio of the partial rate factors for the sulfonation of a halogenobenzene ortho and meta to halogen varies from 17 +/- 1 for the fluoro to 1.5 +/- 0.4 for the iodo substituent.In competition to the sulfonation, 2- and 4-iodotoluene undergo deiodination, The latter process is more important with the 4-isomer and with the protic sulfonating reagent.With the aprotic reagent, the reaction proceeds by direct sulfodeiodination, whereas with the sulfuric acid reagent, it proceeds by initial protiodeiodination and sulfodeprotonation.
