Check Digit Verification of cas no

The CAS Registry Mumber 56047-44-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,0,4 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 56047-44:
(7*5)+(6*6)+(5*0)+(4*4)+(3*7)+(2*4)+(1*4)=120
120 % 10 = 0
So 56047-44-0 is a valid CAS Registry Number.
