Check Digit Verification of cas no

The CAS Registry Mumber 104882-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,8,8 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104882-45:
(8*1)+(7*0)+(6*4)+(5*8)+(4*8)+(3*2)+(2*4)+(1*5)=123
123 % 10 = 3
So 104882-45-3 is a valid CAS Registry Number.
