Check Digit Verification of cas no

The CAS Registry Mumber 1202867-43-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,8,6 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1202867-43:
(9*1)+(8*2)+(7*0)+(6*2)+(5*8)+(4*6)+(3*7)+(2*4)+(1*3)=133
133 % 10 = 3
So 1202867-43-3 is a valid CAS Registry Number.
