129081-52-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 129081-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,0,8 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 129081-52:
(8*1)+(7*2)+(6*9)+(5*0)+(4*8)+(3*1)+(2*5)+(1*2)=123
123 % 10 = 3
So 129081-52-3 is a valid CAS Registry Number.
