We've found references to a book written by accused Syrian Community Rabbi Saul Kassin.
It's title is, The Light of the Law: Guideposts to Biblical Commandments and Their Rabbinic Commentaries, and it was published by Shengold Publishers in 1980 or Schreiber Publishing Incorporated in 1981.
One of the subjects it is associated with in the cataloging information is, "Commandments, Six hundred and thirteen."
The book is cited in the bibliography of a course by Dr. David W. Gill for REGENT COLLEGE Distance Education whose title was, "APPL/INDS 559: BUSINESS ETHICS: ENGAGING MORAL ISSUES IN THE MARKETPLACE."
Our Talmudic analysis: In light of recent arrests, Dr. Gill may wish to revise his syllabus.
Also the cataloging category for Rabbi Kassin's book may need to be amended to read, "Commandments, Six hundred and twelve."
