Here is the link to a cheat sheet for some useful validation rules that you can incorporate in Salesforce.com.


Some of the validation rules that I found useful are
- Postal code is in correct format if the country is Canada or US
- State is valid if the country is Canada or US
- Country is a valid 2 letter ISO code
- Number entered is even or odd number
- Number entered is a multiple of another number
- Phone number is in (999) 999-9999 format
- Date entered is a weekday or weekend
- Date entered is the last day of the month
- Conditionally require a field based on the value of other field
- Only the record owner can make changes to a particular field
- Cross object validation rules
