Check Digit Verification of cas no

The CAS Registry Mumber 18751-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,5 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 18751-49:
(7*1)+(6*8)+(5*7)+(4*5)+(3*1)+(2*4)+(1*9)=130
130 % 10 = 0
So 18751-49-0 is a valid CAS Registry Number.
