Check Digit Verification of cas no

The CAS Registry Mumber 561-19-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 561-19:
(5*5)+(4*6)+(3*1)+(2*1)+(1*9)=63
63 % 10 = 3
So 561-19-3 is a valid CAS Registry Number.
