Check Digit Verification of cas no

The CAS Registry Mumber 1655-45-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1655-45:
(6*1)+(5*6)+(4*5)+(3*5)+(2*4)+(1*5)=84
84 % 10 = 4
So 1655-45-4 is a valid CAS Registry Number.
