121451-91-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121451-91-0 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, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121451-91:
(8*1)+(7*2)+(6*1)+(5*4)+(4*5)+(3*1)+(2*9)+(1*1)=90
90 % 10 = 0
So 121451-91-0 is a valid CAS Registry Number.
