Check Digit Verification of cas no

The CAS Registry Mumber 5216-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5216-55:
(6*5)+(5*2)+(4*1)+(3*6)+(2*5)+(1*5)=77
77 % 10 = 7
So 5216-55-7 is a valid CAS Registry Number.
