125300-80-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125300-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,0 and 0 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125300-80:
(8*1)+(7*2)+(6*5)+(5*3)+(4*0)+(3*0)+(2*8)+(1*0)=83
83 % 10 = 3
So 125300-80-3 is a valid CAS Registry Number.
