Check Digit Verification of cas no

The CAS Registry Mumber 129749-05-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,7,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 129749-05:
(8*1)+(7*2)+(6*9)+(5*7)+(4*4)+(3*9)+(2*0)+(1*5)=159
159 % 10 = 9
So 129749-05-9 is a valid CAS Registry Number.
