125520-68-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125520-68-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,5,2 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 125520-68:
(8*1)+(7*2)+(6*5)+(5*5)+(4*2)+(3*0)+(2*6)+(1*8)=105
105 % 10 = 5
So 125520-68-5 is a valid CAS Registry Number.
