Check Digit Verification of cas no

The CAS Registry Mumber 86137-26-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,1,3 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 86137-26:
(7*8)+(6*6)+(5*1)+(4*3)+(3*7)+(2*2)+(1*6)=140
140 % 10 = 0
So 86137-26-0 is a valid CAS Registry Number.
