Check Digit Verification of cas no

The CAS Registry Mumber 1280199-34-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,1,9 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1280199-34:
(9*1)+(8*2)+(7*8)+(6*0)+(5*1)+(4*9)+(3*9)+(2*3)+(1*4)=159
159 % 10 = 9
So 1280199-34-9 is a valid CAS Registry Number.
