Check Digit Verification of cas no

The CAS Registry Mumber 164589-91-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,4,5,8 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 164589-91:
(8*1)+(7*6)+(6*4)+(5*5)+(4*8)+(3*9)+(2*9)+(1*1)=177
177 % 10 = 7
So 164589-91-7 is a valid CAS Registry Number.
