Check Digit Verification of cas no

The CAS Registry Mumber 1203905-09-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,3,9,0 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1203905-09:
(9*1)+(8*2)+(7*0)+(6*3)+(5*9)+(4*0)+(3*5)+(2*0)+(1*9)=112
112 % 10 = 2
So 1203905-09-2 is a valid CAS Registry Number.
