Check Digit Verification of cas no

The CAS Registry Mumber 120340-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,3,4 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 120340-67:
(8*1)+(7*2)+(6*0)+(5*3)+(4*4)+(3*0)+(2*6)+(1*7)=72
72 % 10 = 2
So 120340-67-2 is a valid CAS Registry Number.
