Check Digit Verification of cas no

The CAS Registry Mumber 120693-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,6,9 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 120693-44:
(8*1)+(7*2)+(6*0)+(5*6)+(4*9)+(3*3)+(2*4)+(1*4)=109
109 % 10 = 9
So 120693-44-9 is a valid CAS Registry Number.
