Check Digit Verification of cas no

The CAS Registry Mumber 128972-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,7 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128972-02:
(8*1)+(7*2)+(6*8)+(5*9)+(4*7)+(3*2)+(2*0)+(1*2)=151
151 % 10 = 1
So 128972-02-1 is a valid CAS Registry Number.
