120811-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120811-05-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,1 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 120811-05:
(8*1)+(7*2)+(6*0)+(5*8)+(4*1)+(3*1)+(2*0)+(1*5)=74
74 % 10 = 4
So 120811-05-4 is a valid CAS Registry Number.
