Check Digit Verification of cas no

The CAS Registry Mumber 1239620-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,6,2 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1239620-71:
(9*1)+(8*2)+(7*3)+(6*9)+(5*6)+(4*2)+(3*0)+(2*7)+(1*1)=153
153 % 10 = 3
So 1239620-71-3 is a valid CAS Registry Number.
