Check Digit Verification of cas no

The CAS Registry Mumber 1045758-82-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,5,7,5 and 8 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1045758-82:
(9*1)+(8*0)+(7*4)+(6*5)+(5*7)+(4*5)+(3*8)+(2*8)+(1*2)=164
164 % 10 = 4
So 1045758-82-4 is a valid CAS Registry Number.
