Check Digit Verification of cas no

The CAS Registry Mumber 56683-78-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,6,8 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 56683-78:
(7*5)+(6*6)+(5*6)+(4*8)+(3*3)+(2*7)+(1*8)=164
164 % 10 = 4
So 56683-78-4 is a valid CAS Registry Number.
