121898-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121898-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,9 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121898-01:
(8*1)+(7*2)+(6*1)+(5*8)+(4*9)+(3*8)+(2*0)+(1*1)=129
129 % 10 = 9
So 121898-01-9 is a valid CAS Registry Number.
