Check Digit Verification of cas no

The CAS Registry Mumber 1029612-22-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,9,6,1 and 2 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1029612-22:
(9*1)+(8*0)+(7*2)+(6*9)+(5*6)+(4*1)+(3*2)+(2*2)+(1*2)=123
123 % 10 = 3
So 1029612-22-3 is a valid CAS Registry Number.
