Check Digit Verification of cas no

The CAS Registry Mumber 138998-63-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,9 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138998-63:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*8)+(2*6)+(1*3)=197
197 % 10 = 7
So 138998-63-7 is a valid CAS Registry Number.
