Check Digit Verification of cas no

The CAS Registry Mumber 98990-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,9 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98990-63:
(7*9)+(6*8)+(5*9)+(4*9)+(3*0)+(2*6)+(1*3)=207
207 % 10 = 7
So 98990-63-7 is a valid CAS Registry Number.
