Check Digit Verification of cas no

The CAS Registry Mumber 80685-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80685-77:
(7*8)+(6*0)+(5*6)+(4*8)+(3*5)+(2*7)+(1*7)=154
154 % 10 = 4
So 80685-77-4 is a valid CAS Registry Number.
