Check Digit Verification of cas no

The CAS Registry Mumber 1257440-20-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,4,4 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1257440-20:
(9*1)+(8*2)+(7*5)+(6*7)+(5*4)+(4*4)+(3*0)+(2*2)+(1*0)=142
142 % 10 = 2
So 1257440-20-2 is a valid CAS Registry Number.
