Check Digit Verification of cas no

The CAS Registry Mumber 123178-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,7 and 8 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 123178-49:
(8*1)+(7*2)+(6*3)+(5*1)+(4*7)+(3*8)+(2*4)+(1*9)=114
114 % 10 = 4
So 123178-49-4 is a valid CAS Registry Number.
