Check Digit Verification of cas no
The CAS Registry Mumber 120109-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 120109-89:
(8*1)+(7*2)+(6*0)+(5*1)+(4*0)+(3*9)+(2*8)+(1*9)=79
79 % 10 = 9
So 120109-89-9 is a valid CAS Registry Number.
