Check Digit Verification of cas no

The CAS Registry Mumber 277-64-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,7 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 277-64:
(5*2)+(4*7)+(3*7)+(2*6)+(1*4)=75
75 % 10 = 5
So 277-64-5 is a valid CAS Registry Number.
