Check Digit Verification of cas no

The CAS Registry Mumber 138995-98-9 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 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138995-98:
(8*1)+(7*3)+(6*8)+(5*9)+(4*9)+(3*5)+(2*9)+(1*8)=199
199 % 10 = 9
So 138995-98-9 is a valid CAS Registry Number.
