Check Digit Verification of cas no

The CAS Registry Mumber 1278446-11-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,8,4,4 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1278446-11:
(9*1)+(8*2)+(7*7)+(6*8)+(5*4)+(4*4)+(3*6)+(2*1)+(1*1)=179
179 % 10 = 9
So 1278446-11-9 is a valid CAS Registry Number.
