Check Digit Verification of cas no

The CAS Registry Mumber 126309-31-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,3,0 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 126309-31:
(8*1)+(7*2)+(6*6)+(5*3)+(4*0)+(3*9)+(2*3)+(1*1)=107
107 % 10 = 7
So 126309-31-7 is a valid CAS Registry Number.
