Check Digit Verification of cas no

The CAS Registry Mumber 1245932-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,9,3 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1245932-57:
(9*1)+(8*2)+(7*4)+(6*5)+(5*9)+(4*3)+(3*2)+(2*5)+(1*7)=163
163 % 10 = 3
So 1245932-57-3 is a valid CAS Registry Number.
