Check Digit Verification of cas no

The CAS Registry Mumber 155959-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,5 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155959-90:
(8*1)+(7*5)+(6*5)+(5*9)+(4*5)+(3*9)+(2*9)+(1*0)=183
183 % 10 = 3
So 155959-90-3 is a valid CAS Registry Number.
