Check Digit Verification of cas no

The CAS Registry Mumber 1422044-89-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,0,4 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1422044-89:
(9*1)+(8*4)+(7*2)+(6*2)+(5*0)+(4*4)+(3*4)+(2*8)+(1*9)=120
120 % 10 = 0
So 1422044-89-0 is a valid CAS Registry Number.
