125743-61-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125743-61-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,7,4 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 125743-61:
(8*1)+(7*2)+(6*5)+(5*7)+(4*4)+(3*3)+(2*6)+(1*1)=125
125 % 10 = 5
So 125743-61-5 is a valid CAS Registry Number.
