121445-53-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121445-53-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,4 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 121445-53:
(8*1)+(7*2)+(6*1)+(5*4)+(4*4)+(3*5)+(2*5)+(1*3)=92
92 % 10 = 2
So 121445-53-2 is a valid CAS Registry Number.
