125443-86-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125443-86-9 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 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125443-86:
(8*1)+(7*2)+(6*5)+(5*4)+(4*4)+(3*3)+(2*8)+(1*6)=119
119 % 10 = 9
So 125443-86-9 is a valid CAS Registry Number.
