Check Digit Verification of cas no

The CAS Registry Mumber 778538-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,7,8,5,3 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 778538-59:
(8*7)+(7*7)+(6*8)+(5*5)+(4*3)+(3*8)+(2*5)+(1*9)=233
233 % 10 = 3
So 778538-59-3 is a valid CAS Registry Number.
