Yes, there are several independent sites where you can find all the information needed to verify. Here you can check how much Ether (ETH) was raised on two different block explorers (both not affiliated with the DAO): http://etherscan.io/address/0xbb9bc244d798123fde783fcc1c72d3... https://etherchain.org/account/0xbb9bc244d798123fde783fcc1c7...

..and to convert that to USD or whatever you can even use https://duckduckgo.com/?q=1+ETH+in+USD&ia=cryptocurrency or check the price directly at one of the exchanges that trades ETH/USD, like https://www.kraken.com/charts.
