Check Digit Verification of cas no

The CAS Registry Mumber 120571-36-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,7 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120571-36:
(8*1)+(7*2)+(6*0)+(5*5)+(4*7)+(3*1)+(2*3)+(1*6)=90
90 % 10 = 0
So 120571-36-0 is a valid CAS Registry Number.
