Check Digit Verification of cas no

The CAS Registry Mumber 56577-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,5,7 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 56577-21:
(7*5)+(6*6)+(5*5)+(4*7)+(3*7)+(2*2)+(1*1)=150
150 % 10 = 0
So 56577-21-0 is a valid CAS Registry Number.
