Check Digit Verification of cas no

The CAS Registry Mumber 680992-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,0,9,9 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 680992-20:
(8*6)+(7*8)+(6*0)+(5*9)+(4*9)+(3*2)+(2*2)+(1*0)=195
195 % 10 = 5
So 680992-20-5 is a valid CAS Registry Number.
