Check Digit Verification of cas no

The CAS Registry Mumber 337-81-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 337-81:
(5*3)+(4*3)+(3*7)+(2*8)+(1*1)=65
65 % 10 = 5
So 337-81-5 is a valid CAS Registry Number.
