Check Digit Verification of cas no

The CAS Registry Mumber 200949-98-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,9,4 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 200949-98:
(8*2)+(7*0)+(6*0)+(5*9)+(4*4)+(3*9)+(2*9)+(1*8)=130
130 % 10 = 0
So 200949-98-0 is a valid CAS Registry Number.
