Check Digit Verification of cas no

The CAS Registry Mumber 121749-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,4 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121749-23:
(8*1)+(7*2)+(6*1)+(5*7)+(4*4)+(3*9)+(2*2)+(1*3)=113
113 % 10 = 3
So 121749-23-3 is a valid CAS Registry Number.
