Check Digit Verification of cas no

The CAS Registry Mumber 1574615-43-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,4,6,1 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1574615-43:
(9*1)+(8*5)+(7*7)+(6*4)+(5*6)+(4*1)+(3*5)+(2*4)+(1*3)=182
182 % 10 = 2
So 1574615-43-2 is a valid CAS Registry Number.
