121089-49-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121089-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121089-49:
(8*1)+(7*2)+(6*1)+(5*0)+(4*8)+(3*9)+(2*4)+(1*9)=104
104 % 10 = 4
So 121089-49-4 is a valid CAS Registry Number.
