Check Digit Verification of cas no

The CAS Registry Mumber 1141365-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,3,6 and 5 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1141365-46:
(9*1)+(8*1)+(7*4)+(6*1)+(5*3)+(4*6)+(3*5)+(2*4)+(1*6)=119
119 % 10 = 9
So 1141365-46-9 is a valid CAS Registry Number.
