Check Digit Verification of cas no

The CAS Registry Mumber 13781-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,8 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13781-61:
(7*1)+(6*3)+(5*7)+(4*8)+(3*1)+(2*6)+(1*1)=108
108 % 10 = 8
So 13781-61-8 is a valid CAS Registry Number.
