Check Digit Verification of cas no

The CAS Registry Mumber 78-65-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78-65:
(4*7)+(3*8)+(2*6)+(1*5)=69
69 % 10 = 9
So 78-65-9 is a valid CAS Registry Number.
