Check Digit Verification of cas no

The CAS Registry Mumber 128505-77-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,0 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128505-77:
(8*1)+(7*2)+(6*8)+(5*5)+(4*0)+(3*5)+(2*7)+(1*7)=131
131 % 10 = 1
So 128505-77-1 is a valid CAS Registry Number.
