Calculate Weighted Digit Sum
Calculates the weighted digit sum from a weighting sequence and one or more numbers or a whole text. Only numbers are interpreted, all other characters will be ignored. At the weighted digit sum, the single ciphers are multiplied with the according numbers of the sequence and then added to each other. When the weighting sequence is run through, it starts anew. Please enter the values of the weighting sequence separated with spaces.
Example: for the weighting sequence 1 2 3 4 5 the weighted digit sum of 987654321 = 1*9 + 2*8 + 3*7 + 4*6 + 5*5 + 1*4 + 2*3 + 3*2 + 4*1 = 115
