Check Digit Verification of cas no

The CAS Registry Mumber 620989-88-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,2,0,9,8 and 9 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 620989-88:
(8*6)+(7*2)+(6*0)+(5*9)+(4*8)+(3*9)+(2*8)+(1*8)=190
190 % 10 = 0
So 620989-88-0 is a valid CAS Registry Number.
