Check Digit Verification of cas no

The CAS Registry Mumber 537041-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,7,0,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 537041-40:
(8*5)+(7*3)+(6*7)+(5*0)+(4*4)+(3*1)+(2*4)+(1*0)=130
130 % 10 = 0
So 537041-40-0 is a valid CAS Registry Number.
