Check Digit Verification of cas no

The CAS Registry Mumber 130043-08-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130043-08:
(8*1)+(7*3)+(6*0)+(5*0)+(4*4)+(3*3)+(2*0)+(1*8)=62
62 % 10 = 2
So 130043-08-2 is a valid CAS Registry Number.
