Check Digit Verification of cas no

The CAS Registry Mumber 1227260-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,2,6 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1227260-46:
(9*1)+(8*2)+(7*2)+(6*7)+(5*2)+(4*6)+(3*0)+(2*4)+(1*6)=129
129 % 10 = 9
So 1227260-46-9 is a valid CAS Registry Number.
