Check Digit Verification of cas no

The CAS Registry Mumber 105454-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,4,5 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105454-46:
(8*1)+(7*0)+(6*5)+(5*4)+(4*5)+(3*4)+(2*4)+(1*6)=104
104 % 10 = 4
So 105454-46-4 is a valid CAS Registry Number.
