Check Digit Verification of cas no

The CAS Registry Mumber 1354575-44-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,4,5,7 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1354575-44:
(9*1)+(8*3)+(7*5)+(6*4)+(5*5)+(4*7)+(3*5)+(2*4)+(1*4)=172
172 % 10 = 2
So 1354575-44-2 is a valid CAS Registry Number.
