Check Digit Verification of cas no

The CAS Registry Mumber 1151549-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,1,5,4 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1151549-57:
(9*1)+(8*1)+(7*5)+(6*1)+(5*5)+(4*4)+(3*9)+(2*5)+(1*7)=143
143 % 10 = 3
So 1151549-57-3 is a valid CAS Registry Number.
