Check Digit Verification of cas no

The CAS Registry Mumber 481048-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,1,0,4 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 481048-21:
(8*4)+(7*8)+(6*1)+(5*0)+(4*4)+(3*8)+(2*2)+(1*1)=139
139 % 10 = 9
So 481048-21-9 is a valid CAS Registry Number.
