# DIN ISO 690 checker: do the numbered references exist?

> DIN ISO 690 is a formatting standard. Quick Check asks something else: does the numbered line exist in Crossref or OpenAlex? Acurio does not generate a DIN list.

## Which job do you need?

| What you need | The answer | Where |
| --- | --- | --- |
| Numbering, order, DIN punctuation | That is formatting. A generator or your guide. Acurio does not format. | Elsewhere |
| Do the numbered entries actually exist? | Paste the list. Existence and retraction. | This page |
| Does [12] support the sentence? | That is the analysis. Numeric markers live in the Run. | Elsewhere |

## Formatting DIN and checking DIN

A clean [12] line can still point at a fabricated work. Quick Check matches every line against the registries.

DIN ISO 690 has variants. The check does not depend on a CSL file.

Orphans between [12] and the list: the orphan-citations mini-app. Claim support: the analysis.

## Frequently asked questions

### Does Acurio generate a DIN ISO 690 list?

No. No generator. This checks an existing list for existence.

### Does Vancouver or IEEE work the same way?

Yes. Numbered lists are the same Quick Check job, whatever the standard is called.

### Is it free?

Quick Check needs no account. The analysis needs credits.
