Check Digit Verification of cas no

The CAS Registry Mumber 104416-46-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,4,1 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104416-46:
(8*1)+(7*0)+(6*4)+(5*4)+(4*1)+(3*6)+(2*4)+(1*6)=88
88 % 10 = 8
So 104416-46-8 is a valid CAS Registry Number.
