Check Digit Verification of cas no

The CAS Registry Mumber 173988-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,9,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 173988-20:
(8*1)+(7*7)+(6*3)+(5*9)+(4*8)+(3*8)+(2*2)+(1*0)=180
180 % 10 = 0
So 173988-20-0 is a valid CAS Registry Number.
