Check Digit Verification of cas no

The CAS Registry Mumber 1257301-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,3,0 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1257301-91:
(9*1)+(8*2)+(7*5)+(6*7)+(5*3)+(4*0)+(3*1)+(2*9)+(1*1)=139
139 % 10 = 9
So 1257301-91-9 is a valid CAS Registry Number.
