Check Digit Verification of cas no

The CAS Registry Mumber 6661-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,6 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6661-57:
(6*6)+(5*6)+(4*6)+(3*1)+(2*5)+(1*7)=110
110 % 10 = 0
So 6661-57-0 is a valid CAS Registry Number.
