Check Digit Verification of cas no

The CAS Registry Mumber 7193-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,9 and 3 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7193-98:
(6*7)+(5*1)+(4*9)+(3*3)+(2*9)+(1*8)=118
118 % 10 = 8
So 7193-98-8 is a valid CAS Registry Number.
