121809-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121809-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,0 and 9 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121809-54:
(8*1)+(7*2)+(6*1)+(5*8)+(4*0)+(3*9)+(2*5)+(1*4)=109
109 % 10 = 9
So 121809-54-9 is a valid CAS Registry Number.
