Check Digit Verification of cas no

The CAS Registry Mumber 139669-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,6 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139669-66:
(8*1)+(7*3)+(6*9)+(5*6)+(4*6)+(3*9)+(2*6)+(1*6)=182
182 % 10 = 2
So 139669-66-2 is a valid CAS Registry Number.
