Check Digit Verification of cas no

The CAS Registry Mumber 1220140-36-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,1,4 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1220140-36:
(9*1)+(8*2)+(7*2)+(6*0)+(5*1)+(4*4)+(3*0)+(2*3)+(1*6)=72
72 % 10 = 2
So 1220140-36-2 is a valid CAS Registry Number.
