1 Introduction

Two classfiles namely cas-sc.cls and cas-dc.cls were written for typesetting articles submitted in journals of Elsevier’s Complex Article Service (CAS) workflow.
1.1 Usage

1.

cas-sc.cls for single column journals.
2. cas-dc.cls for single column journals.
and have an option longmktitle to handle long front matter.
2 Front matter
   

Clip 1: Single column output (classfile: cas-sc.cls).



Clip 2: Double column output (classfile: cas-dc.cls).

The␣front␣matter␣becomes␣complicated␣due␣to␣various␣kinds
of␣notes␣and␣marks␣to␣the␣title␣and␣author␣names.␣Marks␣in
the␣title␣will␣be␣denoted␣by␣a␣star␣($\star$)␣mark;
