Check Digit Verification of cas no

The CAS Registry Mumber 6778-81-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 6778-81:
(6*6)+(5*7)+(4*7)+(3*8)+(2*8)+(1*1)=140
140 % 10 = 0
So 6778-81-0 is a valid CAS Registry Number.
