125115-13-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125115-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,1 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 125115-13:
(8*1)+(7*2)+(6*5)+(5*1)+(4*1)+(3*5)+(2*1)+(1*3)=81
81 % 10 = 1
So 125115-13-1 is a valid CAS Registry Number.
