Check Digit Verification of cas no

The CAS Registry Mumber 60839-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,8,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 60839-99:
(7*6)+(6*0)+(5*8)+(4*3)+(3*9)+(2*9)+(1*9)=148
148 % 10 = 8
So 60839-99-8 is a valid CAS Registry Number.
