Check Digit Verification of cas no

The CAS Registry Mumber 1257901-09-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,9,0 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1257901-09:
(9*1)+(8*2)+(7*5)+(6*7)+(5*9)+(4*0)+(3*1)+(2*0)+(1*9)=159
159 % 10 = 9
So 1257901-09-9 is a valid CAS Registry Number.
