Check Digit Verification of cas no

The CAS Registry Mumber 5054-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,5 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5054-40:
(6*5)+(5*0)+(4*5)+(3*4)+(2*4)+(1*0)=70
70 % 10 = 0
So 5054-40-0 is a valid CAS Registry Number.
