Check Digit Verification of cas no

The CAS Registry Mumber 1202403-64-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,4,0 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1202403-64:
(9*1)+(8*2)+(7*0)+(6*2)+(5*4)+(4*0)+(3*3)+(2*6)+(1*4)=82
82 % 10 = 2
So 1202403-64-2 is a valid CAS Registry Number.
