Check Digit Verification of cas no

The CAS Registry Mumber 412299-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,1,2,2,9 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 412299-21:
(8*4)+(7*1)+(6*2)+(5*2)+(4*9)+(3*9)+(2*2)+(1*1)=129
129 % 10 = 9
So 412299-21-9 is a valid CAS Registry Number.
