Check Digit Verification of cas no

The CAS Registry Mumber 1111644-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,1,1,6,4 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1111644-77:
(9*1)+(8*1)+(7*1)+(6*1)+(5*6)+(4*4)+(3*4)+(2*7)+(1*7)=109
109 % 10 = 9
So 1111644-77-9 is a valid CAS Registry Number.
