Check Digit Verification of cas no

The CAS Registry Mumber 55950-32-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,5 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55950-32:
(7*5)+(6*5)+(5*9)+(4*5)+(3*0)+(2*3)+(1*2)=138
138 % 10 = 8
So 55950-32-8 is a valid CAS Registry Number.
