121399-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121399-80-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,3,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121399-80:
(8*1)+(7*2)+(6*1)+(5*3)+(4*9)+(3*9)+(2*8)+(1*0)=122
122 % 10 = 2
So 121399-80-2 is a valid CAS Registry Number.
