Check Digit Verification of cas no

The CAS Registry Mumber 120476-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,7 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120476-20:
(8*1)+(7*2)+(6*0)+(5*4)+(4*7)+(3*6)+(2*2)+(1*0)=92
92 % 10 = 2
So 120476-20-2 is a valid CAS Registry Number.
