Check Digit Verification of cas no

The CAS Registry Mumber 6181-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,8 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6181-57:
(6*6)+(5*1)+(4*8)+(3*1)+(2*5)+(1*7)=93
93 % 10 = 3
So 6181-57-3 is a valid CAS Registry Number.
