Check Digit Verification of cas no

The CAS Registry Mumber 135301-01-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,3,0 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 135301-01:
(8*1)+(7*3)+(6*5)+(5*3)+(4*0)+(3*1)+(2*0)+(1*1)=78
78 % 10 = 8
So 135301-01-8 is a valid CAS Registry Number.
