130265-25-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130265-25-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,6 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 130265-25:
(8*1)+(7*3)+(6*0)+(5*2)+(4*6)+(3*5)+(2*2)+(1*5)=87
87 % 10 = 7
So 130265-25-7 is a valid CAS Registry Number.
