13520-07-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 13520-07-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,2 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13520-07:
(7*1)+(6*3)+(5*5)+(4*2)+(3*0)+(2*0)+(1*7)=65
65 % 10 = 5
So 13520-07-5 is a valid CAS Registry Number.
