Check Digit Verification of cas no

The CAS Registry Mumber 875680-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,6,8 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 875680-99:
(8*8)+(7*7)+(6*5)+(5*6)+(4*8)+(3*0)+(2*9)+(1*9)=232
232 % 10 = 2
So 875680-99-2 is a valid CAS Registry Number.
