Check Digit Verification of cas no

The CAS Registry Mumber 91-72-5 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91-72:
(4*9)+(3*1)+(2*7)+(1*2)=55
55 % 10 = 5
So 91-72-5 is a valid CAS Registry Number.
