Check Digit Verification of cas no

The CAS Registry Mumber 57562-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,5,6 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57562-07:
(7*5)+(6*7)+(5*5)+(4*6)+(3*2)+(2*0)+(1*7)=139
139 % 10 = 9
So 57562-07-9 is a valid CAS Registry Number.
