Check Digit Verification of cas no

The CAS Registry Mumber 148-75-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 8 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 148-75:
(5*1)+(4*4)+(3*8)+(2*7)+(1*5)=64
64 % 10 = 4
So 148-75-4 is a valid CAS Registry Number.

Process for aryl-quinone and aryl-naphthoquinone diazide sulfonic acids

-

, (2008/06/13)

A process for the preparation of aryl-diazide-sulfonic acids by a series of sequential in-situ process steps. The process comprises the nitrosation of a hydroxyarylsulfonic acid; conversion of the nitroso-derivative to a sulfamate which is then diazotized to the diazide. Temperature and pH are maintained in predetermined ranges to maintain the reaction products in solution without the formation side-products or the need to isolate intermediates. The process of the invention is particularly useful in the preparation of light-sensitive materials such as naphthoquinonediazide sulfonic acids which are used in the preparation of photoresist compositions. The invention provides a high purity product at a high material efficiency, high equipment utilization, low effluent discharge, and reduced cost.

Excited-State Proton-Transfer Kinetics: A Theoretical Model

Arnaut, Luis G.,Formosinho, Sebastiao J.

, p. 685 - 691 (2007/10/02)

The intersecting-state model is applied to excited state proton-transfer reactions.The results are consistent with those previously obtained for the analogous ground-state reactions.The transition-state bond order n* is similar in the ground and excited states: carbon acids have lower n* than nitrogen or oxygen acids.The mixing entropy parameter λ is found to be lower for excited-state than ground-state reactions.The mechanistic implications of this are discussed.
