Check Digit Verification of cas no
The CAS Registry Mumber 109121-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,1,2 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 109121-05:
(8*1)+(7*0)+(6*9)+(5*1)+(4*2)+(3*1)+(2*0)+(1*5)=83
83 % 10 = 3
So 109121-05-3 is a valid CAS Registry Number.
