Check Digit Verification of cas no

The CAS Registry Mumber 5661-56-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,6 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5661-56:
(6*5)+(5*6)+(4*6)+(3*1)+(2*5)+(1*6)=103
103 % 10 = 3
So 5661-56-3 is a valid CAS Registry Number.
