Check Digit Verification of cas no

The CAS Registry Mumber 81520-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81520-91:
(7*8)+(6*1)+(5*5)+(4*2)+(3*0)+(2*9)+(1*1)=114
114 % 10 = 4
So 81520-91-4 is a valid CAS Registry Number.
