Check Digit Verification of cas no

The CAS Registry Mumber 1591802-91-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,9,1,8,0 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1591802-91:
(9*1)+(8*5)+(7*9)+(6*1)+(5*8)+(4*0)+(3*2)+(2*9)+(1*1)=183
183 % 10 = 3
So 1591802-91-3 is a valid CAS Registry Number.
