Check Digit Verification of cas no

The CAS Registry Mumber 134255-85-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,5 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134255-85:
(8*1)+(7*3)+(6*4)+(5*2)+(4*5)+(3*5)+(2*8)+(1*5)=119
119 % 10 = 9
So 134255-85-9 is a valid CAS Registry Number.
