Check Digit Verification of cas no

The CAS Registry Mumber 136258-85-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,2,5 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 136258-85:
(8*1)+(7*3)+(6*6)+(5*2)+(4*5)+(3*8)+(2*8)+(1*5)=140
140 % 10 = 0
So 136258-85-0 is a valid CAS Registry Number.
