9 Application. Your company wants to develop a barcode scanner to help track the locations of production equipment. Every room is assigned a five-digit ID, and every piece of equipment is assigned a six-digit ID, neither of which can start with 0. You decide to encode these ID's as a nine-digit barcode. You pad the beginning of room ID's with 333 and the beginning of equipment ID's with 66. Then, you assign the last digit of the barcode as a check digit so that the sum of all digits is congruent to 5 modulo 7. Determine the nine-digit barcode number for a room with the ID number 16795.
