Share transfer stamp duty

Dear All,

Presently Share Transfer Stamp Duty is 0.25 paise per Rs. 100 Consideration amount.

I want to know is there any cap of maximum duty to be paid on Share Transfer.

For Example

If Stamp duty to be paid on share Transfer is Rs. 50,00,000 (worked out on the basis of 0.25 paise per Rs 100 Consideration amount)

Is it mandatory to pay Rs. 50,00,000/- or is there any maximum limit provided in the Act for lesser amount?

Thanks & Regards
