Not necessarily. If the tens digit is 5 or more there will be a carryover from the tens to the hundreds making the hundreds bigger by 1. For example, 53*102=5300+106=5406. The units digit isn't twice the hundreds. Also, if the units digit is 5 or more, the units digit of the product is going to be 0, 2, 4, 6, 8. For example, 46*102=4692. The units digit is only 2 while the hundreds is 6. But if we keep the 2-digit number's digits below 5 then the units digit on the product will be twice the hundreds: e.g., 43*102=4386.
