Check Digit Verification of cas no

The CAS Registry Mumber 1262150-75-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,1,5 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1262150-75:
(9*1)+(8*2)+(7*6)+(6*2)+(5*1)+(4*5)+(3*0)+(2*7)+(1*5)=123
123 % 10 = 3
So 1262150-75-3 is a valid CAS Registry Number.
