113520-57-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113520-57-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,2 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 113520-57:
(8*1)+(7*1)+(6*3)+(5*5)+(4*2)+(3*0)+(2*5)+(1*7)=83
83 % 10 = 3
So 113520-57-3 is a valid CAS Registry Number.
