121998-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121998-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,9 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121998-34:
(8*1)+(7*2)+(6*1)+(5*9)+(4*9)+(3*8)+(2*3)+(1*4)=143
143 % 10 = 3
So 121998-34-3 is a valid CAS Registry Number.
