Check Digit Verification of cas no

The CAS Registry Mumber 267899-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,8,9 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 267899-13:
(8*2)+(7*6)+(6*7)+(5*8)+(4*9)+(3*9)+(2*1)+(1*3)=208
208 % 10 = 8
So 267899-13-8 is a valid CAS Registry Number.
