Check Digit Verification of cas no

The CAS Registry Mumber 1266569-20-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,5,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1266569-20:
(9*1)+(8*2)+(7*6)+(6*6)+(5*5)+(4*6)+(3*9)+(2*2)+(1*0)=183
183 % 10 = 3
So 1266569-20-3 is a valid CAS Registry Number.
