Check Digit Verification of cas no

The CAS Registry Mumber 16499-05-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,4,9 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16499-05:
(7*1)+(6*6)+(5*4)+(4*9)+(3*9)+(2*0)+(1*5)=131
131 % 10 = 1
So 16499-05-1 is a valid CAS Registry Number.
