125442-80-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125442-80-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,4 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125442-80:
(8*1)+(7*2)+(6*5)+(5*4)+(4*4)+(3*2)+(2*8)+(1*0)=110
110 % 10 = 0
So 125442-80-0 is a valid CAS Registry Number.
