Validate the validation criteria in Fixed width multi schema file

I have a fixed width file with multiple record types as provided below:

A record block starts with Record Type 01 and ends with Record Type 14. There could be multiple rows for Record Type 13 and 14. But Record Type 01 and 11 will have one row every time.

The first 2 bytes represent "Record Type" eg - 00,01,11,13,14,99.

The next 6 bytes represent "Account No" eg - 778899, 997788

After "Account Number" field the schema of each record type is different.

Record Type = 11 has all the Master level Information of Record Type 13 and 14.

Record Type = 11 has Group Entity Name(in Short) eg TATA, RELI and Date (in DDMMYY) 120822,080822

Record Type = 13 has Business Entity Name (20 Bytes) under the Group Entity

Record Type = 14 has the Business Entity Name (20 Bytes), Share Holders Name (20 Bytes) in order of their holdings.

The Validation Rules are as below:

Each Record Block should start with Record Type 01.

The Record Type 11 should be there immediately after Record Type 01.

The Record Type 13 Should be immediately after Record Type 11.

The Record Type 14 should be immediately after Record Type 13.

All the records in a block must contain the same Account No.

Could you please help me with the design for the above validation criteria. Thanks a lot.
