Check Digit Verification of cas no

The CAS Registry Mumber 1257428-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1257428-47:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*2)+(3*8)+(2*4)+(1*7)=169
169 % 10 = 9
So 1257428-47-9 is a valid CAS Registry Number.
