120533-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120533-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,3 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120533-93:
(8*1)+(7*2)+(6*0)+(5*5)+(4*3)+(3*3)+(2*9)+(1*3)=89
89 % 10 = 9
So 120533-93-9 is a valid CAS Registry Number.
