Check Digit Verification of cas no

The CAS Registry Mumber 1189786-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,7,8 and 6 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1189786-69:
(9*1)+(8*1)+(7*8)+(6*9)+(5*7)+(4*8)+(3*6)+(2*6)+(1*9)=233
233 % 10 = 3
So 1189786-69-3 is a valid CAS Registry Number.
