Check Digit Verification of cas no

The CAS Registry Mumber 129201-03-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,2,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 129201-03:
(8*1)+(7*2)+(6*9)+(5*2)+(4*0)+(3*1)+(2*0)+(1*3)=92
92 % 10 = 2
So 129201-03-2 is a valid CAS Registry Number.
