Check Digit Verification of cas no

The CAS Registry Mumber 121906-80-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,0 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121906-80:
(8*1)+(7*2)+(6*1)+(5*9)+(4*0)+(3*6)+(2*8)+(1*0)=107
107 % 10 = 7
So 121906-80-7 is a valid CAS Registry Number.
