Check Digit Verification of cas no

The CAS Registry Mumber 884868-77-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,4,8,6 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 884868-77:
(8*8)+(7*8)+(6*4)+(5*8)+(4*6)+(3*8)+(2*7)+(1*7)=253
253 % 10 = 3
So 884868-77-3 is a valid CAS Registry Number.
