Check Digit Verification of cas no

The CAS Registry Mumber 5757-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,5 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5757-80:
(6*5)+(5*7)+(4*5)+(3*7)+(2*8)+(1*0)=122
122 % 10 = 2
So 5757-80-2 is a valid CAS Registry Number.
