121809-91-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121809-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121809-91:
(8*1)+(7*2)+(6*1)+(5*8)+(4*0)+(3*9)+(2*9)+(1*1)=114
114 % 10 = 4
So 121809-91-4 is a valid CAS Registry Number.
