Getting SMILES from CAS number
« on: August 24, 2013, 01:24:16 AM »
Dear all,
Kindly provide info on online systems that help generate SMILES codes from CAS numbers. Reference to experts in this field would also be welcome.
thanks in anticipation.

I do not think this is doable as CAS numbers do not have anything to do with the structure and contain no structural information.

dear all
can anyone help me with preparing SMILES code for following two compounds

(a) 7-hydroxy-3-methyl-4-phenyl coumarin;
(b) 4-(2-phenylethyl)-7-hydroxy coumarin

Forum rules state that you must have at least attempted the problem.

See above link for details.

 Can you draw the structures for us first please?

This will provide advice on SMILES generation once you have the structures.

Even our short SMILES tutorial can be enough for these compounds.

1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

There are various databases you can search by compound name or CAS number that will provide the SMILES code for your compound:

Texas carbon ? :)

c1ccc2c(c1)C=CC(=O)o2

(ironically, what you have entered is what Accelrys Draw gives too. May be a bug)
