Check Digit Verification of cas no

The CAS Registry Mumber 90026-87-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,2 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90026-87:
(7*9)+(6*0)+(5*0)+(4*2)+(3*6)+(2*8)+(1*7)=112
112 % 10 = 2
So 90026-87-2 is a valid CAS Registry Number.
