125405-90-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125405-90-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,4,0 and 5 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125405-90:
(8*1)+(7*2)+(6*5)+(5*4)+(4*0)+(3*5)+(2*9)+(1*0)=105
105 % 10 = 5
So 125405-90-5 is a valid CAS Registry Number.
