Check Digit Verification of cas no

The CAS Registry Mumber 1046471-55-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,6,4,7 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1046471-55:
(9*1)+(8*0)+(7*4)+(6*6)+(5*4)+(4*7)+(3*1)+(2*5)+(1*5)=139
139 % 10 = 9
So 1046471-55-9 is a valid CAS Registry Number.
