1193111-13-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1193111-13-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,3,1,1 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1193111-13:
(9*1)+(8*1)+(7*9)+(6*3)+(5*1)+(4*1)+(3*1)+(2*1)+(1*3)=115
115 % 10 = 5
So 1193111-13-5 is a valid CAS Registry Number.
