Check Digit Verification of cas no

The CAS Registry Mumber 57991-82-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,9 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 57991-82:
(7*5)+(6*7)+(5*9)+(4*9)+(3*1)+(2*8)+(1*2)=179
179 % 10 = 9
So 57991-82-9 is a valid CAS Registry Number.
