Check Digit Verification of cas no

The CAS Registry Mumber 55213-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,1 and 3 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55213-35:
(7*5)+(6*5)+(5*2)+(4*1)+(3*3)+(2*3)+(1*5)=99
99 % 10 = 9
So 55213-35-9 is a valid CAS Registry Number.
