125158-60-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125158-60-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,5 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125158-60:
(8*1)+(7*2)+(6*5)+(5*1)+(4*5)+(3*8)+(2*6)+(1*0)=113
113 % 10 = 3
So 125158-60-3 is a valid CAS Registry Number.
