Check Digit Verification of cas no

The CAS Registry Mumber 185913-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,9,1 and 3 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 185913-97:
(8*1)+(7*8)+(6*5)+(5*9)+(4*1)+(3*3)+(2*9)+(1*7)=177
177 % 10 = 7
So 185913-97-7 is a valid CAS Registry Number.
