Check Digit Verification of cas no

The CAS Registry Mumber 786-57-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,8 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 786-57:
(5*7)+(4*8)+(3*6)+(2*5)+(1*7)=102
102 % 10 = 2
So 786-57-2 is a valid CAS Registry Number.
