Check Digit Verification of cas no

The CAS Registry Mumber 128141-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,4 and 1 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128141-34:
(8*1)+(7*2)+(6*8)+(5*1)+(4*4)+(3*1)+(2*3)+(1*4)=104
104 % 10 = 4
So 128141-34-4 is a valid CAS Registry Number.
