121451-82-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121451-82-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,4,5 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121451-82:
(8*1)+(7*2)+(6*1)+(5*4)+(4*5)+(3*1)+(2*8)+(1*2)=89
89 % 10 = 9
So 121451-82-9 is a valid CAS Registry Number.
