113519-13-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113519-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,1 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113519-13:
(8*1)+(7*1)+(6*3)+(5*5)+(4*1)+(3*9)+(2*1)+(1*3)=94
94 % 10 = 4
So 113519-13-4 is a valid CAS Registry Number.
