Check Digit Verification of cas no

The CAS Registry Mumber 1730-19-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,3 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1730-19:
(6*1)+(5*7)+(4*3)+(3*0)+(2*1)+(1*9)=64
64 % 10 = 4
So 1730-19-4 is a valid CAS Registry Number.
