Check Digit Verification of cas no

The CAS Registry Mumber 1245820-40-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,8,2 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1245820-40:
(9*1)+(8*2)+(7*4)+(6*5)+(5*8)+(4*2)+(3*0)+(2*4)+(1*0)=139
139 % 10 = 9
So 1245820-40-9 is a valid CAS Registry Number.
