Check Digit Verification of cas no

The CAS Registry Mumber 189263-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,2,6 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 189263-69:
(8*1)+(7*8)+(6*9)+(5*2)+(4*6)+(3*3)+(2*6)+(1*9)=182
182 % 10 = 2
So 189263-69-2 is a valid CAS Registry Number.
