Check Digit Verification of cas no

The CAS Registry Mumber 20056-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,5 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 20056-44:
(7*2)+(6*0)+(5*0)+(4*5)+(3*6)+(2*4)+(1*4)=64
64 % 10 = 4
So 20056-44-4 is a valid CAS Registry Number.
