Check Digit Verification of cas no

The CAS Registry Mumber 90107-88-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,0 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90107-88:
(7*9)+(6*0)+(5*1)+(4*0)+(3*7)+(2*8)+(1*8)=113
113 % 10 = 3
So 90107-88-3 is a valid CAS Registry Number.
