Check Digit Verification of cas no

The CAS Registry Mumber 10489-75-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 10489-75:
(7*1)+(6*0)+(5*4)+(4*8)+(3*9)+(2*7)+(1*5)=105
105 % 10 = 5
So 10489-75-5 is a valid CAS Registry Number.
