Check Digit Verification of cas no

The CAS Registry Mumber 1428552-93-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,8,5,5 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1428552-93:
(9*1)+(8*4)+(7*2)+(6*8)+(5*5)+(4*5)+(3*2)+(2*9)+(1*3)=175
175 % 10 = 5
So 1428552-93-5 is a valid CAS Registry Number.
