Check Digit Verification of cas no

The CAS Registry Mumber 137451-85-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,5 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 137451-85:
(8*1)+(7*3)+(6*7)+(5*4)+(4*5)+(3*1)+(2*8)+(1*5)=135
135 % 10 = 5
So 137451-85-5 is a valid CAS Registry Number.
