Check Digit Verification of cas no

The CAS Registry Mumber 128924-12-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,2 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128924-12:
(8*1)+(7*2)+(6*8)+(5*9)+(4*2)+(3*4)+(2*1)+(1*2)=139
139 % 10 = 9
So 128924-12-9 is a valid CAS Registry Number.
