Check Digit Verification of cas no

The CAS Registry Mumber 851-77-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 851-77:
(5*8)+(4*5)+(3*1)+(2*7)+(1*7)=84
84 % 10 = 4
So 851-77-4 is a valid CAS Registry Number.
