Check Digit Verification of cas no

The CAS Registry Mumber 17891-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,9 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 17891-56:
(7*1)+(6*7)+(5*8)+(4*9)+(3*1)+(2*5)+(1*6)=144
144 % 10 = 4
So 17891-56-4 is a valid CAS Registry Number.
